Thanks for the quick reply.  Ultimately, the refund amount from 2020 applied to 2021 was negative because I had to make a payment in July 2021 for balance due owed from 2020.   Would the correct way to deal with this be to enter the payment I need in the field "Balance due on your 2020 state taxes paid in 2021" since amount of refund from 2020 to 2021 was ultimately zero?
