I said I was going to mail in my return but since have found my AGI from last year and would like to e file. Can I still do this?

You can but only if you have NOT mailed your return.  If you already mailed it and then you e-file, your return will be delayed, probably for a really long time.  

Sign into your return and click on Take me to my return.  On the Tax Home page, scroll down until you see ''Add a State''.  This will unlock your return.  Then you go to FILE, change your filing method to E-file and proceed.   

How do I change from File by Mail to E-file in TurboTax Online?  see image.
