After filling out forms online, I’m not even sure if I e-filed, or if I have to mail my return. Help.

You complete your tax return by finishing all 3 Steps in the File section. In Step 3, to e-file your tax return, you must click on the large Orange button labeled "Transmit my returns now".

After completing the File section and e-filing your tax return you will receive two emails from TurboTax. The first email when your tax return was transmitted and the second email when the tax return has either been accepted or rejected.

Did you do this?

I don’t think so. I ended up printing. But there’s no instruction on mailing it.
