After you file

@Ma8  Or when you said you want your W-2, do you really mean your tax return?   We do see a lot of people who are confused and think "W-2"  means the same thing as tax return, and it does not mean the same thing.  

And are you looking for 2017 or 2018?  When you add on to someone else's thread it is harder for us to know what you are asking.

2018

Note:  Every year, before mid-October, print a copy of your current year tax return and save it as a tax file and pdf, too.  That way you will have it when you need it for school, a loan, next year’s tax return, etc. without going through a lot of aggravation (and expense)  to get it.
