form 8829 line 10 is populating with unknown and incorrect information

[cindybear]

I'm getting a negative number on this Deductible Mortgage Interest line 10 and cannot remove it.    The amount should be zero as lines 16-22 hold expenses for the entire home which are then used to calculate line 24 for the percentage used for the home office.  This amount on line 10 is throwing an error on the 'Check for errors' feature.  I don't know where Turbo Tax is pulling this info from, or how to remove it.
