To correct your overtime information in TurboTax Online, you need to go back into the W-2 section where you first entered your work information. Start by selecting Wages & Income and then click Edit next to the W-2 for the employer where you worked the overtime. If you entered the overtime in Box 14, update the amount there and make sure the category is still set to Overtime. If it was not on your W-2, simply continue past the W-2 entry screens until you reach the Let’s check for other situations screen. Ensure the box for Overtime is checked and click Continue to reach the interview page where you can re-type your overtime premium amount.
