Amend TurboTax 8606?

[julia-vu-ucsf]

My CPA never filed an 8606 for my 2022 taxes (that was my first year making non deductible contributions to traditional IRA) so I just had him submit one. I used TurboTax for 2023 tax year and I filed a 8606 for that one.

Do I have to amend the 8606 for 2023 now that I just submitted one for 2022 since I imagine the changes will carry over ? If yes, can someone help walk me through it using TurboTax so I don’t mess up?

On your 2023 return, did you enter your 12/31/2022 non-deductible contributions basis from 2022 to start Form 8606 that year?

If so, you don't need to Amend.   If the starting value on your 2023 8606 was incorrect, you can submit Form 8606 with 1040X.
