@Todd-AH
Just ran a test tax return with state income taxes withheld on a W-2 of $3,000. State estimated taxes paid in 2021 of $5,000. Amount paid with a 2020 state income tax return of $3,000.
The total of $11,000 was entered on Schedule A Line 5a.
I would suggest that you return to the sections where you entered the payments and verify that the correct amounts have been entered.
