I am currently stuck and unable to submit my tax forms electronically. I think my problem is similar to @sandy4042.
On form 2210 part two, line 10, tax withheld smart worksheet, the first box for a calculated withholding for January one through April 15 remains red. On line 11 everything is correct but on the easy step it only captures the amount from the first quarter as opposed to the entire year and it claims that there is an error so I cannot submit my taxes.
I exercised an ISO and retired in the middle of the year and paid 110% of my tax burden from 2020 so as to avoid a penalty. I still have a small one however. If I don't use this form, my tax penalty will be higher. Any suggestions?
