And then.....make sure you go ALL THE WAY through the FILE section in order to e-file your tax return. You have to click a big orange button that says "Transmit my returns now" in order to e-file.
When you e-file your federal return you will receive two emails from TurboTax. The first one will say that your return was submitted. The second email will tell you if your federal return was accepted or rejected. If you e-filed a state return, there will be a third email to tell you if the state accepted or rejected your state return.
