Why does deductions and credits show mortgage interest before I've entered any?

I am using the online website tool and under deductions and credits there is a summary of everything and one item is Mortgage Interest and Refinancing (Form 1098). I have not entered my 1098 info yet, but it is showing $1000s of dollars in interest already. Where is it getting this from? If I enter my 1098 info, it gets added to this huge base value  resulting in a very incorrect deduction.
