I'll be withholding federal tax on my monthly retirement income in 2025. How do I enter the withholding amount on the 2025 Estimated Taxes and Form W-4 Worksheet?

[MinhT1]

Federal taxes withheld from your monthly retirement income will be reported in box 4 of your 2025 form 1099-R, which you will receive beginning of 2026.

By entering this form 1099-R on your tax return, taxes withheld will be recorded and you will get the credit against your tax liability.

You do not have to enter these taxes withheld anywhere else on your tax return.

On the other hand, if you choose to pay quarterly estimated taxes (instead of withholding taxes), you have to enter these payments on your 2025 tax return.
