SALT deduction

[Frustrated_in_California]

in 2025 we paid California estimated income taxes for tax year 2024.  When I enter the amount into TurboTax, it appears on Federal Schedule A with a 17.5% reduction.  No matter what number I enter, it appears on Schedule A reduced by approximately the same percentage.  But if I enter the amount as a LOCAL estimated tax for tax year 2024 paid in 2025, it appears on Schedule A without any problem in the proper amount.  Our total SALT deductions are less than the $40,000 SALT cap.  Our MAGI is well below the $500,000 threshold.  

I have tried re-entering the numbers several times but I always have the same problem.

Thanks for any suggestions!
