I am attempting to amend a 2020 Tax return....here are the "help" instructions.

(1) open the return already filed.  (I did)

(2) Immediately save the return using a different name.  (I did)

(3) You need to be working in the FILED Return and not the COPY.  ( I am)

(4) Go to the INfo Worksheet and select Efile Federal Amended Return.  ( I did)

(5) Select Form 1040-X  ( I did)

(6) The "Original amount column A will show the amounts that were originally reported on the Form 1040 you already filed after you make an entry for an area of change in the tax return.  ( It doesn't)

I entered $25,000 in the correct amount for estimated taxes....Nothing happens

ed $25,000
