No, for most accurate tax calculations, you should enter each separate 1098 as it's own separate entry. Therefore, once you are done entering one, then select "Add A Lender" when you complete the full entries for this first 1098 and are at the "Home Loan Deduction Summary" page. Even if the Lender is the same, if the loan is a separate loan (different account number), then they should be entered separately. As far as the Real Estate Taxes Paid, this typically only falls onto one or two (two, if you refinanced) 1098 Forms. Therefore, you would enter the total amounts shown on each separate 1098 Form just like the mortgage interest paid information.
