While amending my 2019 federal return, Turbotax is asking me to correct the payment date to any time between 01/27/2020 and 07/15/2020. Why?

I mean payment will take place on November 1, 2021. Why should I enter 2020?

Sounds like something is stuck in the program from last year.  Try updating your software and see if it changes.  If not, just put in the date that it wants if that is what you need to do to finish your 2019 amend.

Hope you realize that you are going to have to mail that 2019 amended return.  You will not be able to e-file it.   So you could pay the tax due on the IRS site or you could write a check or money order and include it with the tax return when you mail it.

In the FILE tab  choose to mail in the return then go to the print center to get the forms & instructions needed to mail in the return.
