thanks for your reply @KatrinaLO...
I've followed these steps, and cannot find an option to add an estimated tax payment. all the options are related to changing withholdings, payments with an extension, or carryovers from previous year to be applied to 2019.
could you walk me thru the steps to add an estimated tax payment that I left off the original return?
