After the last update I noticed that when running the error check before e-filing a return with federal estimated payments to be electronically withdrawn the first quarter estimated payment now says "Installment 1 of 0.00 due 05/17/2021" and then installment 2 due on 06/15/2021 is the total of 1st and 2nd quarters amounts.  IRS did not extend the estimated tax payment due dates (as of yet) so why is ProSeries set up this way?  Won't the 1st quarter estimated payment be late?
