Then do as I originally suggested. Report 1 1098 in TurboTax. Box 1 would be the total interest from Box 1 of all 4 1098s. Box 2 would be the amount of the current outstanding mortgage principal.
You are correct that if you put all 3 in you are going to be over your limit. The only way to get the mortgage interest credit is to enter the way I state above.
