My itemized deduction is not picking up all of the state income taxes paid during the year?

[LeticiaF1]

There are some limits on the itemized deduction for state and local taxes.  In 2025, the total deduction for state and local income, or sales taxes and property taxes is limited to $40,000 or $20,000 if  you are married filing separately.  There is also limits based on your income, your deduction might be reduced if your modified AGI is more than $500,000 or $250,000 if married filing separately.

Perfect.  that was it.

I also do not know where to access supplemental information in TurboTax like the detailed calculation of tax due.  I used to find this very useful especially now with the various phase outs, capital gains, and additional tax.
