Credit for past non-deductible contributions to an IRA via 8606 form

While preparing my 2024 return, I attempted to get credit for past non-deductible contributions to my IRA via the 8606 form.  I have used TurboTax for many years and have always been able to get this credit.  For the current return (for 2024), TurboTax reported that I do not qualify for the credit.  I think TurboTax is wrong (a bug?)).  What can I do to resolve this issue?
