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 W-2 or last paycheck stub to import. From your W-2, you need the information from Box 1 (gross income) or year to date gross income from your last paycheck stub and your employer's EIN. Sometimes, you will need the Control Number, which is in box D of the W-2.
