Property taxes are deductible but only as an itemized deduction. You get either the standard deduction or itemized deductions, not both. If your standard deduction is 12.2K, then you need itemized deductions of more than 12.2K before you will see any change.
TurboTax will use the higher number which will maximize your tax return. Once the total of your itemized deductions (mortgage interest, property taxes, medical expenses, charity donations, etc.) exceeds your standard deduction (of your filing status), TurboTax will make the switch for you.
