Tax return review states:
You have chosen to have the following installment(s) of your client's estimated taxes for tax year 2021 paid by electronic funds withdrawal:
Installment 1 of 0.00 due 05/17/2021
Installment 2 of $$ (installment 1 and 2 amounts added together) due 06/15/2021
Installment 3 ...

Installment 1 due date is 04/15/2021 and the amount in the return is NOT zero.

Can @ProSeries confirm the review information the program is giving is indeed wrong?  It appears to be doing the same as for tax year 2019, which does not apply to tax year 2020.
