I'm trying to efile a 1040X for 2023 but receive error message "not transmitted; amended return failed the tax submission amended return validation step"
What do I need to do?
Efiling wont be open until Jan 27th.
I knew that for 2024 returns. I didn't know it applied to 2023 Amended
Thank you
The MeF system is closed, doesnt matter the year.
