Once you filed the original return, you cannot just add another W-2 to the existing return without Amending the return.  Remove the 2nd W-2 and then wait till approx mid February to do the Amended return -which must be printed, signed and mailed to IRS.

Once the return has been filed it cannot be stopped (unless you get extremely lucky and IRS would reject it for some reason).

So you have to wait for the return to be processed and you get your refund.

Then approx mid-February you can sign back into TurboTax and do the Amended return.
