Hi Rick:

I got it, no way arround it but to pay the $2,000

Now, the question is: can the $2,000 be added to the total payment paid for 2021?

In this case the refund on the new 1040 will become again $10,000 instead of $8,000 which will be applied any way to 2022 estimated tax payment. (IN THIS CASE THE APPLIED AMOUNT WILL REMAIN THE SAME ON BOTH RETURNS)
