Code TT in box 12 of the W-2 form (starting in 2026) represents qualified overtime reported to the employer. Your employer used codes that don't apply to 2025 which is the reason why you don't see the cod TT in the dropdown. Skip inputting that number in box 12 and report your overtime in the follow-up screens that appear after you finish entering your W-2.
In TurboTax Online, this is how you enter the qualified overtime premium:
- After entering your form W-2, you'll see a screen titled Let's Check for Other Situations
- Put a checkmark on Overtime and click Continue
- Follow the TurboTax questionnaire to enter your qualified overtime premium
- This deduction will transfer to Schedule 1-A of your form 1040, with that amount flowing to line 13b of your form 1040.
Refer to the TurboTax article How do I enter overtime pay in TurboTax Online? and I Worked Overtime This Year — My W-2 Pay Doesn’t Show it. for detailed instructions to enter your overtime.
