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!
After attempting to replicate the situation you described and failing to do so, it would be useful to have a diagnostic copy of your tax data file. The diagnostic file will not contain personally identifiable information, only numbers related to your tax forms.

Thank you for providing your diagnostic file and token number.
I was able to take a look at your file and I understand why it appears that the state estimated payment made in 2025 for 2024 is being reduced. It appears to be reduced on Schedule A because it actually is reduced because you received a refund for your 2024 state taxes.
Since a portion of your total tax payments and withholdings to the state for your 2024 return was actually paid in 2025, a portion of the tax refund you received must be allocated to 2025 as well. Then, that allocated amount of your refund is used to adjust the payment that was made in 2025. Without making this adjustment, it would be possible for a taxpayer to artificially inflate their deductions for the current tax year by overpaying their 4th quarter estimated payment in January.
In your case, the amount of your state refund for 2024 divided by your total tax payments and withholdings did come out to be about 17.6%. Therefore, the estimated payment made in 2025 was reduced by that same percentage before it was included on Schedule A as part of your itemized deductions.
The State and Local Income Tax Worksheet (St Refund Wks) included as part of your return shows the numbers involved in the calculation. You can print this form by choosing it specifically in the Print Menu option after your TurboTax Online fee has been paid.
