You may have to ask your employer, or check your pay stubs. For 2026, the overtime must be reported in one official way, but for 2025, there is no official method, and I don;t know if your employer used the correct method.
Overtime is only deductible to the extent it is required by the Fair Labor Standards Act. This means the "half-time" when you are paid time-and-a-half for working over 40 hours. If you make $20/hour and work 45 hours, your deductible OT is 5 hr X $10. If you are paid overtime for working more than 8 hours a day but don't go over 40 hours a week, that is not deductible. If you are paid more than time and a half, or you are paid shift differentials for working nights, weekends, or holidays, that is also not deductible, because it is an employee benefit or a contract benefit but is not required by the FLSA. And if you are classified as an "Exempt" supervisory worker, your OT is not deductible because it is not required by the FLSA.
If you don't know how your employer calculated the amount in box 14, you should ask them or calculate it yourself from your pay stubs.
