While reviewing my 1040 form, line 25c shows federal income tax withheld from "other forms". I cannot figure out where this came from. Please help.

Hi Rich - I have discovered the exact same issue with my 2022 return (thanks to the IRS).  I have scrutinzed every input and form on TT - same as you described - and cannot find where the "Other Tax Paid" came from.  I will remove this entry and see if I get no error, as you did.

I noted this same issue while reviewing my 2023 return tonight, and then went back to my 2022 return and found it there as well.  For my returns, the amount correlates with Form 8959 Part V, which is a “Medicare tax withholding reconciliation” — apparently the TT program has decided that I have overpaid my Medicare taxes and is giving credit for a small portion of it.

Your situation may differ, but hopefully this will help some find the source of their “other forms” payments on line 25c of form 1040.

If you have the desktop software, look to see if you have an Other Income statement...here is a screenshot of part of it"

I cant find the source of 1040 line 25c either.  Token code is 1250843
