TurboTax imports W-2  information directly from many banks, employers and financial institutions. If the address that populated is different from your W-2 we always recommend that you use what is on the paper copy of your Form W-2. 

To Edit the W-2 in TurboTax Online:

• Go to the Federal Taxes tab and select Wages & Income.

• Then go to Wages & Salaries.

• Select Start/Revisit next to Wages and Salaries.

• Select Edit next to the W-2 you need to correct.
