May I change state return ( I just finished my returns) so I can e-file it instead of mailing it? I did e-file federal return. There is a small state credit

IF the return has not yet been submitted...

Open the return you want to change

Underneath the blue TurboTax logo bar you will see 5 white/grey tabs

| PERSONAL INFO | FEDERAL TAXES | STATE TAXES | REVIEW | FILE |

Select  the FILE tab (in the program, not above)

Select File a Return

You will then have the option to select e-file

You will also have an option of having the refund Directly Deposited into your account or a check mailed.  You will see those options as you progress thru the screens.

Good luck!
