A 2015 W-2 can only be reported on a 2015 tax return, nowhere else.  

If you filed a 2015 tax return using TurboTax then see this TurboTax support FAQ on amending a 2015 tax return - https://ttlc.intuit.com/questions/3410543-how-do-i-amend-change-or-correct-a-2015-return-in-turbotax

An amended tax return, Form 1040X, can only be printed and mailed, it cannot be e-filed.
