The easiest way is to ask your employer for another copy. You can also ask Social Secuirty, but there is a fee. If you just need to visually see the information, you can look at the return you printed or kept on your computer. TurboTax provides worksheets with that information.
TurboTax does not have a copy of your physical W-2 (nor does TurboTax have copies of your 1099's).
