What do I do with a w2 from last year that I never filed?

[ModestaL]

Are you referring to a W-2 from 2016? If so, did you already file your taxes from 2016?

If you haven't filed your 2016 tax return, you can use the TurboTax CD/Download software to paper-file a your tax return.Order the CD/Download software here.

If you have already filed your 2016 tax return and have another W-2 to add, you would have to amend your return to do so. Please see FAQ (click on see entire answer) and select 2016 tax year for instructions for amending that return: https://ttlc.intuit.com/replies/3288565
