Thank you, @CatinaT1 and @ DoninGA
Got it - so I did make an error in clicking on Amend (but canceled - no harm done). However, when I click on Add a State and then search for Estimated Payments, I'm still getting the same result: I can edit 2019 estimated payments made, I can reprint my 2020 vouchers, but I don't see an option to set up future auto-drafted payments towards 2020 taxes. I did search through a bit more of the responses when searching for Estimated Payments and found a FAQ directing me to the IRS Payment website if I don't want to just mail in the vouchers. Guess I was expecting something a little slicker these days to be embedded in this program than printing and mailing paper vouchers, but I think the answer to this thread is: TurboTax provides you with the paper vouchers for your 2020 quarterly estimated tax payments. When such payments are due, one may either use the printed vouchers and mail in payments, or go to the IRS Payments site and pay electronically (same for state quarterly estimate income taxes if your state provides a utility for payment of quarterly taxes).
