INTERNAL CONTROL RPT

REPORT OF INDEPENDENT REGISTERED PUBLIC
ACCOUNTING FIRM

To the Shareholders and Board of Trustees of BlackRock
Municipal 2020 Term Trust and BlackRock Florida
Municipal 2020 Term Trust:

In planning and performing our audit of the financial statements
of BlackRock Municipal 2020 Term Trust and BlackRock
Florida Municipal 2020 Term Trust (the "Funds") as of
December 31, 2018 and for the period from May 1, 2018
through December 31, 2018 and from August 1, 2018 through
December 31, 2018, respectively , in accordance with the
standards of the Public Company Accounting Oversight Board
(United States) (PCAOB), we considered the Funds' internal
control over financial reporting, including controls over
safeguarding securities, as a basis for designing our auditing
procedures for the purpose of expressing our opinion on the
financial statements and to comply with the requirements of
Form N-CEN, but not for the purpose of expressing an opinion
on the effectiveness of the Funds' internal control over
financial reporting. Accordingly, we express no such opinion.

The management of the Funds is responsible for establishing
and maintaining effective internal control over financial
reporting. In fulfilling this responsibility, estimates and
judgments by management are required to assess the expected
benefits and related costs of controls. A company's internal
control over financial reporting is a process designed to provide
reasonable assurance regarding the reliability of financial
reporting and the preparation of financial statements for
external purposes in accordance with generally accepted
accounting principles. A company's internal control over
financial reporting includes those policies and procedures that
(1) pertain to the maintenance of records that, in reasonable
detail, accurately and fairly reflect the transactions and
dispositions of the assets of the company; (2) provide
reasonable assurance that transactions are recorded as necessary
to permit preparation of financial statements in accordance with
generally accepted accounting principles, and that receipts and
expenditures of the company are being made only in
accordance with authorizations of management and directors of
the company; and (3) provide reasonable assurance regarding
prevention or timely detection of unauthorized acquisition, use,
or disposition of a company's assets that could have a material
effect on the financial statements.

Because of its inherent limitations, internal control over
financial reporting may not prevent or detect misstatements.
Also, projections of any evaluation of effectiveness to future
periods are subject to the risk that controls may become
inadequate because of changes in conditions or that the degree
of compliance with the policies or procedures may deteriorate.

A deficiency in internal control over financial reporting exists
when the design or operation of a control does not allow
management or employees, in the normal course of performing
their assigned functions, to prevent or detect misstatements on a
timely basis. A material weakness is a deficiency, or a
combination of deficiencies, in internal control over financial
reporting, such that there is a reasonable possibility that a
material misstatement of the company's annual or interim
financial statements will not be prevented or detected on a
timely basis.

Our consideration of the Funds' internal control over financial
reporting was for the limited purpose described in the first
paragraph and would not necessarily disclose all deficiencies in
internal control that might be material weaknesses under
standards established by the PCAOB. However, we noted no
deficiencies in the Funds' internal control over financial
reporting and its operation, including controls for safeguarding
securities, that we consider to be a material weakness, as
defined above, as of December 31, 2018.

This report is intended solely for the information and use of
management and the Board of Trustees of the Funds and the
Securities and Exchange Commission and is not intended to be
and should not be used by anyone other than these specified
parties.

BLACKROCK MUNICIPAL 2020 TERM TRUST (the “Fund”)

File No. 811-21181

Item G.1.b.iii: New or amended investment advisory contracts

Attached please find a copy of the Closed-End Fund Master Advisory Fee Waiver Agreement between the Fund and BlackRock Advisors, LLC.

Closed-End Fund Master Advisory Fee Waiver Agreement

This MASTER ADVISORY FEE WAIVER AGREEMENT (this “Agreement”) is made as of the 2nd day of December, 2016, by and among BlackRock Advisors, LLC (the “Adviser”) an “Adviser”) and each investment company listed on Schedule A attached hereto (each, a “Fund”).

WHEREAS, each Fund is registered under the Investment Company Act of 1940, as amended (the “1940 Act”), as a closed-end management company, and is organized as a statutory trust under the laws of the State of Delaware, a limited liability company under the laws of the State of Delaware, a business trust under the laws of the Commonwealth of Massachusetts or a corporation under the laws of the State of Maryland;

WHEREAS, the Adviser and each Fund are parties to investment advisory agreements (the “Advisory Agreements”), pursuant to which the Adviser provides investment advisory services to each Fund in consideration of compensation as set forth in each Advisory Agreement (the “Advisory Fee”); and

WHEREAS, the Adviser has determined that it is appropriate and in the best interests of each Fund and its interestholders to waive part of each Fund’s Advisory Fee as set forth in Schedule B attached hereto (the “Fee Waiver”). Each Fund and the Adviser, therefore, have entered into this Agreement in order to effect the Fee Waiver for each Fund at the level specified in Schedule B attached hereto on the terms and conditions set forth in this Agreement.

NOW, THEREFORE, in consideration of the mutual covenants set forth herein and other good and valuable consideration, the receipt of which is hereby acknowledged, the parties hereto agree as follows:

1. Contractual Fee Waiver. During the Term (as defined in Section 3 below), the Adviser shall waive a portion of its Advisory Fee with respect to each Fund as set forth in Schedule B attached hereto.

2. Voluntary Fee Waiver/Expense Reimbursement. Nothing herein shall preclude an Adviser from contractually waiving other fees and/or reimbursing expenses of any Fund, voluntarily waiving Advisory Fees it is entitled to from any Fund or voluntarily reimbursing expenses of any Fund as the Adviser, in its discretion, deems reasonable or appropriate. Any such voluntary waiver or voluntary expense reimbursement may be modified or terminated by the Adviser at any time in its sole and absolute discretion without the approval of the Fund’s Board of Trustees or Board of Directors, as the case may be.

3. Term; Termination.

3.1 Term. The term (“Term”) of the Fee Waiver with respect to a Fund shall begin on December 2, 2016 (or such other date as agreed to in writing between the Adviser and the Fund) and end with respect to a Fund after the close of business on the date set forth on Schedule A (or such other date as agreed to in writing between the Adviser and the Fund) unless the Fee Waiver is earlier terminated in accordance with Section 3.2. The Term of the Fee Waiver with respect to a Fund may be continued from year to year thereafter provided that each such continuance is specifically approved by the Adviser and the Fund (including with respect to the Fund, a

majority of the Fund’s Trustees or Directors, as the case may be, who are not “interested persons,” as defined in the 1940 Act, of the Advisers (the “Non-Interested Directors”)). Neither the Adviser nor a Fund shall be obligated to extend the Fee Waiver with respect to the Fund.

3.2 Termination. This Agreement may be terminated prior to expiration by any Fund with respect to such Fund without payment of any penalty, upon 90 days’ prior written notice to the Adviser at its principal place of business (or at an earlier date as may be agreed to by both parties); provided that, such action shall be authorized by resolution of a majority of the Non-Interested Directors of such Fund or by a vote of a majority of the outstanding voting securities of such Fund.

4. Miscellaneous.

4.1 Captions. The captions in this Agreement are included for convenience of reference only and in no other way define or delineate any of the provisions hereof or otherwise affect their construction or effect.

4.2 Interpretation. Nothing herein contained shall be deemed to require a Fund to take any action contrary to the Fund’s Declaration of Trust or Articles of Incorporation, as the case may be, or Bylaws, or any applicable statutory or regulatory requirement to which it is subject or by which it is bound, or to relieve or deprive the Fund’s Board of Trustees or Board of Directors, as the case may be, of its responsibility for and control of the conduct of the affairs of the Fund.

4.3 Limitation of Liability. The obligations and expenses incurred, contracted for or otherwise existing with respect to a Fund shall be enforced against the assets of such Fund and not against the assets of any other Fund.

4.4 Definitions. Any question of interpretation of any term or provision of this Agreement, including but not limited to the computations of average daily net assets or of any Advisory Fee, and the allocation of expenses, having a counterpart in or otherwise derived from the terms and provisions of the relevant Advisory Agreement between the Adviser and the Fund or the 1940 Act, shall have the same meaning as and be resolved by reference to such Advisory Agreement or the 1940 Act, as applicable, and to interpretations thereof, if any, by the United States Courts or in the absence of any controlling decision of any such Court, by rules, regulations or orders of the Securities and Exchange Commission (“SEC”) issued pursuant to the 1940 Act. In addition, if the effect of a requirement of the 1940 Act reflected in any provision of this Agreement is revised by rule, regulation or order of the SEC, that provision will be deemed to incorporate the effect of that rule, regulation or order. Otherwise the provisions of this Agreement will be interpreted in accordance with the substantive laws of the State of New York.

IN WITNESS WHEREOF, the parties have caused this Agreement to be signed by their respective officers as of the day and year first above written.
