This item is difficult to determine, and appears to be weakly supported in TurboTax. California FTB Publication 1001, page 17 does NOT indicate that you cannot adjust for the actual taxes paid if you were limited to the $10,000.00 state property tax limitation. The following text is the FTB 1001 instructions for other taxes, inclusive of property taxes:
3) Other taxes:
Federal law allows a deduction for state and local income taxes or state and local general sales taxes. California specifically disallows the deduction for state and local income tax (including limited partnership tax and income or franchise tax paid by corporations) and State Disability Insurance (SDI) or state and
local general sales tax.
Differences between Federal and California Law: The TCJA limited the deduction for state and local taxes to $10,000 ($5,000 if married filing separately) for the aggregate of state and local income taxes and property taxes. California does not conform.
What to do for California: Enter the amount deducted for federal on Schedule CA (540), Part II or Schedule CA (540NR), Part III, line 5a, column B.
NOTE: I had to open worksheet "Tax and Int Wks" in the Federal tax section and fill in the amount paid for my primary property and the amount paid for my second home. This was then automatically carried over to the California calculations.
