Turbotax Deluxe Not Combining my Mortgage Interest from my 2 1098s

Last year (so the year I'm filing for) my mortgage lender sold my loan to another company, so I ended up with two 1098 forms this year. I put both forms into Turbotax. One has a low mortgage interest amount because it was the old one that got sold in February (let's go with $1000 for the purpose of explaining this) and one has a high mortgage interest amount since it was my lender for the rest of the year (let's say $7000 for the explanation). When I get to the part where it summarizes my deductions and pits itemized vs standard, it only displays the low $1000 low mortgage interest instead of combining them into $8000. And I confirm it does this on the tax forms as well.

 

How do I get Turbotax to properly combine the two values to put on my itemized deduction?
