Get your taxes done using TurboTax

I don't think there is another $20 fee for anything.  You might be seeing a $40 fee in addition to the $20 state efile.  So it might actually be $60.  There is a $40 Pay with Refund Service charge if you want the state fee deducted from your refund.

Go back though the File tab and watch the screens.  There is one at the end that's easy to click on the wrong button.  Watch out for this screen.
