Do I need to amend my return if I forgot to file a 1098 - mortgage interest?

My mortgage was transferred mid-year and I only filed the 1098 provided by the final lender thinking that it would have the information for the entire year. I saw that the previous lender's 1098 had different numbers. When I entered the new info, it did not change my refund. Do I need to mail the return in any way?
