Why is summary Mortgage interest displayed wrong (too high!)

On the summary page it shows my “Mortgage Interest, Refinancing and Insurance” as 16,506.  But I just entered the Form 1098 for my mortagge, and that is nearly double the Mortgage Interest, that I JUST entered (9,644).   I didn’t refinance and don’t have mortgage insurance.  It used to be Turbotax would show you where it’s calculated number came from, but now everything is a complete mystery. 

 

Is this some carry over from previous year because of tax law changes?  Why is Turbotax so mysterious?
