Omitted SSI from 2021 taxes. IRS sent paperwork, bill, we signed. paid in '23. How to update 2021 in Turbotax? Don't need to file again, need it to know we paid Fed due!

Started Ammended return, can't understand how to close it. TT thinks we owe $5K. No so, we paid, Feds processed & completed Oct '23.  None of "Tell us about...ammended return" choices applicable. We filed outside of Turbotax, its processed. Done. Just want to clear TT..
