Turbotax not allowing update of property taxes

If your initial property taxes paid was entered along with your mortgage information on your Form 1098, then you will need to edit the information through the Form 1098 entry.  

The property tax field for 'additional homes and land' is just that, for additional homes and land, not your primary residence.

Thank you for the explanation.  I did not know you needed to go back and redo the input for the entire set of information pertaining to the property.
