I wanna change and file electronically. The instruction say that: Just go back to TurboTax, selec the File tab, then select the E-file category. But I can´t go there

If your account says Printed or Ready to Mail that means you have to actually print out your tax return and mail it to the IRS yourself. If you have not mailed it yet you can try to switch to efile.

In TurboTax Online, sign in to your account.
Select Tax Home in the left menu.
Scroll down to Your tax returns & documents.
Select 2023, and then select Add a State (you're not actually adding a state, this just gets you back into your return).

Thanks a lot, I was afraid to lose my return. I couldn't do it without your help! Thanks again!
