I have on my w2 but on 2017 what I can do?

If your employer gave you a W-2 that has tax year 2017 instead of 2020, contact them to get a 2020 W-2.

If you received a W-2 that has a tax year of 2017 and you didn't file an income tax return in 2017 or you didn't include the 2017 W-2 on your tax return, select one of the options:

• To file a 2017 income tax return, see How do I prepare a 2019, 2018, or 2017 tax return?
• To amend a 2017 income tax return, see How to amend (change or correct) a return you already filed?

Three weeks after you finish and send in your amended return, you can check the status using the Where's My Amended Return? online tool or by calling the toll-free telephone number 866-464-2050. 

Generally, Form 1040-X,  Amended U.S. Individual Income Tax Return, must be filed within three years of the date the original return was filed, or within two years of the date the tax was paid, whichever is later.

Keep in mind: You have 3 years from the date you filed your return or 2 years after you paid the tax due (whichever is later) to file an amendment.
