I'm trying to figure out what you're asking. If you are saying the SSN on the W-2 doesn't match your real SSN? The correct answer is to get a corrected W-2 from the company. Given that the new tax deadline is tomorrow, 7/15/20, you'll want to file an extension request, Form 4868, Application for Automatic Extension of Time To File U.S. Individual Income Tax Return. This automatically gives you an extra 3 months to file your return, until 10/15/20. Remember that filing the extension doesn't delay the tax payment date. Only when you have to file your returns. You'll have to declare any taxes due with the Form 4868, and pay them by tomorrow to avoid penalties and interest.
