In 2023 I had a little excess 401K contribution that I discovered just before filing the taxes in April 2024. I contacted the benefits admin and they withdrawn the excess fund and the interest before filing deadline. I added the excess amount correctly in 2023 return as though I got a 1099-R with code 'P'. However since no actual 1099-R was generated by the benefits admin company by that time, I used my employers TIN as payer TIN while inputing the 1099-R data in Turbotax software then.
Now (in 2025) that I got the actual 1099-R forms (two of them) from the benefits admin company, I see that they have used a different TIN as payer TIN. This year I am inputting that data in Turbotax software and it is only adding the interest. That seems right.
So in essence the excess fund that I had shown in 2023 return was CORRECT, but just that I used a different payer TIN. My understanding is that since no tax was deducted in 1099-R, the 1099-R data that I typed in for 2023 return was not part of the forms filed by Turbotax for 2023 (in April 2024).
So I do not need to take any steps to amend the 2023 return for this ONLY reason to correct the incorrect payer TIN I used since that data (TIN) was not even part of the return.
Is this correct understanding?
