If it's a 2016 W-2, it will need to be filed on your 2016 return. If you have already filed the return, you just need to wait until the IRS has accepted your return and you have received the refund. Once you get the refund, then you will need to file an amended return to add the additional W-2 to your return. 

After you have received your refund, you can go here and get instructions https://ttlc.intuit.com/questions/3061514 for amending that return.
