Already filed 2016 but used the wrong year, 2015, what will happen?

When filing my 2016 taxes, using Turbo tax, I unintentionally did it by using my 2015 w2 form. Now that it's filed what will happen since there was a different amount from 2015 to 2016,

You will need to wait to see if your return is accepted or rejected. If rejected, you may correct and resubmit. If it is accepted, you will need to file an amendment.

Please reference this TurboTax FAQ for how to amend.

Then, to delete your previous entry and add your W-2 while working in amendment, please reference this TurboTax FAQ. At Step 4, click the delete button next to the W-2 you entered previously. Then, enter your 2016 W-2.
