E- filing 2019 amended return

[BR4026]

I am currently trying to E-filing my 2019 federal amended return using TurboTax. One of the last steps to this process is entering todays signature which I am assuming is the current date you are E-filing ie...03/03/2021. Unfortunately TurboTax will not accept a date beyond 12/31/2020 for this step. This program glitch seemingly makes it impossible to transmit your returns.

TurboTax closed e-filing of 2019 tax returns after October 2020.  The 2019 amended tax return can only be printed and mailed using TurboTax.  You will need to change the way the return is being filed to File by Mail, not E-filing.

I appreciate a response on this so quickly even if it's not what I wanted to hear. I spent 1.5 hours on the phone the other day with TurboTax customer service and still had no answer why it would not work.
