Phase out for overtime deduction

I am filing MFJ and my spouse received OT pay in 2025. Our AGI is only slightly over the $300,000 amount which is when the deduction starts to phase out. TurboTax calculated the OT deduction correctly based on her end-of-year paystub, but it then reports that the maximum deductible amount for us is $0 due to the phaseout. By my calculation, the maximum deductible amount should be something less than IRS $25,000 MFJ maximum but not zero since our AGI falls in the phaseout range. Any help explaining why Turbotax is not letting claim any amount for this deduction?
