Where do I enter my property taxes

[jerry2000]

Property taxes are an itemized deduction. The Free version of Turbotax does not support itemized deductions. But before you upgrade to a paid version, consider that your property tax may not provide a tax benefit. To get a tax benefit from itemized deductions, all of them added together must be more than your standard deduction.
