This occurs when there are supporting details for property tax in your 2010 return and that return is transferred into your 2011 return.
How to Solve
Mac Solution: Simply double-click the Property Tax entry field and you'll be able to add supporting details and the amount of any property taxes paid in 2011.
iPad Solution: Unfortunately TurboTax for iPad doesn't handle supporting details at this time. You will need to transfer your return into TurboTax for Desktop.
