Deductions & credits

I have 3 because I refinanced and the new loan was assigned to a different lender. So, I have 1098s from (i) my original lender, (ii) my post-refi lender, and (iii) my post-refi assigned lender. Each lists my approximate outstanding mortgage principal. Do I only list the outstanding mortgage principal for the original lender 1098 (since that is the only one of the three loans that was outstanding on 1/1/20)?
