No one has addressed my situation. I get the same error message.
I have several refis on primary home mortgage and a vacation home purchased in Sep. 2019. But the Turbo Tax (Deluxe) Home Mortgage Interest Worksheet is calculating average balance for each refi as half of outstanding mortgage principal. If I calculate using other IRS methods, I am under the $750K limit. But TurboTax won't let me change the amount. Any help out there? Thanks.
