1099-R used incorrect TIN - do I need to amend

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 I contacted the benefits admin and they withdrawn the excess fund and the interest before filing deadline.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?

No, you do not need to amend your 2023 return because you used the wrong TIN. You reported the excess on your 2023 return and should be able to see the excess deferral on line 1 h of your 2023 Form 1040. You don't need to do anything else.
