1) Noticed that on NJ Info form Part VI the "Due Date" for each voucher is reflecting 2020 due dates...I just overrode the due dates to 2021, is there a programing error?

2) On efile pending, same client has first quarter estimated tax payment (electronic) showing as a separate line item, however column for amount due on regular return is listed as well as the amount of the 1st installment for quarterly estimated payment...will this duplicate the 2020 NJ 1040 amount due which is also electronically set up for payment?
