I paid a total or $6512.43 combined real estate tax and vehicle tax but Turbotax says I reached the $10000 limit?

Did you have state income tax withheld from your earnings? For most people, that is the largest component of state and local taxes.

SALT is State And Local Tax.  Which includes property tax, any state tax paid like for last year’s return and includes any state withholding from your W2s and any 1099s you have. And any taxes in W2 box 14 and 19 like SDI or VDI. You can only deduct up to 10,000 (5,000 MFS) for SALT State and Local Taxes.
