Turbo Tax will not allow me to correct propery tax amount. How do I correct that?

You may bet trying to change it a different place than where you entered it.  Property tax can be entered in the Mortgage Interest Deduction entry screen, or it can be entered in the "Property Taxes" section of the Deductions & Credits.  If you entered it from your Form 1098 in the mortgage interest section you need to Update that section in order to edit it.
