Underpay penalty: Sum of the 4 qtrs adds up to the total withholding for the year. Federal review shows numbers don't add up and only shows 3/4 quarters on the form.

what is on Line 25d for Form 1040? is that the number you are trying to tie to????

Be careful ... when entering in the estimated payments for the fed & state ... the January 2022 payment belongs to the 2021 tax return and the January 2023 payment belongs to the 2022 return  ...  so the Jan 2022 payment will not be part of the 2022 tax return.

Depends on whether you paid an estimated tax or you paid taxes with an extension request.
