I have this same problem - my excess contributions are for the 2023 tax year.
My 401k fund management company redistributed my excess contributions back to me in February of 2024.
They sent me the check, but THEY WITHHELD THE STATE AND FEDERAL TAXES!
They are telling me they'll send the 1099-R in Jan of 2025, because the disbursement occurred in the 2024 tax year.
So when I go through the process you outlined above, TurboTax doesn't give me the option of adding how much was withheld in state and federal taxes, but only provides the place for adding the gross ammount of 'additional income'. And the total tax-owed number indicator adjusts by about what is additionally owed.
I've already paid for this tax by way of the 401k manager's withholding it before my cash out check.
I need help on what to do here?
Thanks,
