Can Ohio amended tax returns be e-filed?

[TomK2023 · Accepted solution]

Maybe.  Yes, you can e-file your amended Ohio return if you originally e-filed your 2025 return using TurboTax and it has already been accepted by the state.

Do not start the amendment until your original return has been accepted (not just submitted) by both the IRS and the State of Ohio.  If rejected, you can just log back in and make any necessary changes.

Amend State Return:

1. Open your return.
2. Look for the option "Amend (change) return."
3. The program will walk you through the federal amendment first (if applicable), then it will automatically transfer those changes to your Ohio return.
4. At the very end, TurboTax will tell you if your Ohio return is eligible for e-file. However, if it says "File by Mail," you will need to print, sign, and mail the IT 1040X.

Please note: Ohio may require a brief explanation of why you are amending (e.g., "Received a corrected W-2" or "Forgot to claim a credit").

If you mail it, you must include any new W-2s or 1099s that changed your tax math.

If you owe money with your amendment, you can  include a check/money order (or pay electronically even if you end up mailing the paper form.
