You will have to calculate your overtime premium. For tax years 2025–2028, you can only deduct the overtime premium—the portion of your pay that exceeds your regular hourly rate—up to $12,500 ($25,000 for joint filers). Since your overtime rate is a unique 4.2x multiplier, the standard TurboTax automated calculations for "time-and-a-half" (1.5x) or "double-time" (2.0x) will not work correctly for you. You should manually calculate your eligible premium and enter it directly.
