Turbo Tax supposedly uploaded my W2 but I cannot find it.

TurboTax doesn't have your W-2 forms, but if your payroll provider is a TurboTax Import Partner, you should be able to import it. You will need information from your last paycheck stub to import. You need the year to date gross income from your last paycheck stub and your employer's EIN. 

For additional information, review the TurboTax Help articles Will I be able to import my W-2 before I get it in the mail? and How do I import or enter my W-2?
