Amend Federal and State return

Amend Federal and State return - Backdoor Roth IRA

Hi all,

After I filed my 2024 taxes, I realized I never contributed to my Roth IRA. My key question is related to how to update my state tax returns on turbotax and for which state.

Details of current state:

I completed contribution to Roth IRA via backdoor Roth on April 1 2025 for tax year 2024. Traditional IRA started and ended at $0. This all occurred in 2025. I understand I will receive my 1099-R in 2025 and I will show the conversion for 2024 and 2025 to Roth IRA when I file for Tax year 2025.

I was able to amend my Federal Return through TurboTax to generate 8606 and I e-filed an amended return. It was already accepted by the IRS as of today 4/3. I don't believe I have further action on the Federal return.

I was a partial resident in NY and then later moved to NJ in February 2024. As of December 31st, 2024, I am NJ resident and currently NJ resident.
- My Backdoor Roth IRA contribution and conversion all occurred while I am a NJ resident on April 1st 2025 as noted above.
I spoke with a turbo tax expert today on 4/3/25 and they advised I do not need to submit an amended state tax return to show the Traditional IRA contribution, but this did not sound right to me.
- As of now, I have not submitted any Amended State returns, but I have submitted an amended Federal return.

Key Questions:

For my state returns, do I need to submit an amended Tax return for each state (New York and New Jersey) even though I am currently a NJ resident and all contributions were made in 2025 while I am a NJ resident.
- I ask this because I was a partial NY resident, but unsure if NY will need to see this as I won't need to file a 2025 NY state return.

If I need to submit a NY or NJ amended state tax return to show the tradition IRA contribution, how do I go about showing this? I do not see this on the state amended forms.
