Filing Amended Tax Return After CPA Error

Hi experts,

 

I’m trying to file an amendment for my 2025 federal and state tax returns and could use some guidance.

 

My original return was filed by my CPA without my final sign-off, and it appears there was an error - my backdoor Roth IRA contribution was double-taxed. I prepared a corrected return using TurboTax and attempted to file it on April 15, but it was rejected because my CPA had already submitted a return on my behalf.

 

I’ve reviewed the instructions for filing an amendment, but I don’t see the “File an Amendment” option in my TurboTax account. I’m wondering if this is because the original return was not filed through TurboTax.

 

I’ve tried contacting my CPA but haven’t received a response for the past two weeks, so I’m exploring alternative options. Is there a way to file an amended return through TurboTax in this situation, or would you recommend a different approach?

 

Thank you very much for your help.
