The 2021 Form 1040 adds a line for taxes paid that were not Estimated Tax Payments.
It is Schedule 3 Line 13z.
Earlier versions of Form 1040 did not have such a line so you have to rely on the IRS to recognize and apply your account's prior payments for that tax year that are not marked "Estimated Tax"..
OR
look for the "Other" line on Schedule 3.
