Do I Need to Mail Amended Returns After E-filing?

[dliang2025]

I e-filed my amended federal and California tax returns for 2024 using TurboTax. According to Turbotax , both the federal and California return show as "accepted” now. My original returns were e-filed via Turbotax.

I would like to if I still need to mail paper copies if accepted, or is e-filing sufficient? I want to avoid duplicate filings. Please advise or request additional details if needed.

If you e-filed, you do not need to mail the return.  As long as it shows it was accepted, there is nothing more for you to do.

But TurboTax prompted me to mail despite showing accepted. I am afraid that mailing paper copies could risk duplicate filings.

What was the exact wording TurboTax used to prompt you to mail it? Is it the form or documents that you changed?  

 When you go on the IRS and CA sites, does it show that the AMENDED return has been accepted?  If it does, then you would not mail the amended forms.  But it is possible depending on what you changed or added that you need to mail in supporting documentation.
