Deductions & credits

I also have two 1098 forms one for I sold my home and another for the new home. The first 1098 form in which I sold the home shows a balance in Box 2 which I paid off when I got new loan for new home from another lender. My question is how do I list the 1st 1098 on the home I sold? Do I mark Primary Home, Second Home or other?  where does it show I sold it?
