I have 2 1098 for my house since the bank sold the loan how do I mark one as the most recent

The most recent loan is the financial institution that bought the loan. . Enter all the information from the first 1099-Mortgage Interest Form  (original loan). Mark that it was sold when TurboTax asks. Next, enter the second 1099-Mortgage Interest Form. Don't enter that the second one was refinanced since the mortgage wasn't refinanced, just sold.

The outstanding mortgage principal will be in box 2 of the current servicer.  There shouldn't be an outstanding mortgage principal for the original servicer since the loan was transferred.

Refer to the TurboTax article How do I handle multiple 1098 mortgage forms in TurboTax Online? for additional information.
