It is my understanding that taxpayers have until May 17th to pay 2020 tax balances due as well as file their individual income tax returns. 

I just tried to input a date after April 15th but before May 17th as the payment date of a Federal balance due on Input Screen 3 and got an error saying the date had to before 4/16/2021.   Has anyone else had an issue with this?  Any advice?
