Get your taxes done using TurboTax

Normally, the ordinary income portion of the employee stock sale is reported on your W-2 form in box 1. It may or may not have a reference to it in box 14. It is not subject to social security tax, so you won't see it in box 3. If so, you just need to enter your W-2 form to report the ordinary income. If not, you can enter it as Other Income in the Less Common Income section of TurboTax,  which is in the Wages and Income section. Look for Miscellaneous Income at the bottom of the list, and on the next screen choose Other Reportable Income.
