I filed but just found out I’m having another W2 mailed to me by the end of the week. What do I need to do?

If you've already filed, you need to wait to see if the your tax return is accepted by the IRS.  They have announced that they will begin accepting tax returns on January 28.  So, there is a possibility that your return could be rejected for some reason.  If so, you will be able to add the additional W-2, correct whatever caused your return to be rejected, and re-file. If your return is accepted, you will need to file an amended return to add your additional W-2.  The TurboTax Amend function will be available some time in February.

You need to WAIT until you find out if your return has be REJECTED or ACCEPTED.
Then, it is BEST if you wait until you actually receive the refund (or payment due is taken from your account) based on your already filed return;  then you can start the amendment process

Above all  DO NOT DO ANYTHING until you find out if your return is rejected or accepted.
