I just fixed my return by entering in the correct W-2. Turbo Tax says I have to send it in by mail. I didn't see any instructins for that. I just clicked continue.

To file your return by mail, follow these instructions:

1. Print your return. (Don't forget to save a copy to your computer. TurboTax Online saves a copy in the cloud; this is extra protection for you.)
2. Sign the return and date it.
3. Attach a copy of your W-2s and any 1099-Rs to the front of the return. Note that most of these forms print out with three or four copies. Just send one copy of each W-2 or 1099-R.
4. Mail your return to the appropriate address below.
