I met same issue for refinancing debt interests. I refinanced for same property in year 2019 and TT showed combined amount for both loans as average loan amount . As it's greater than 1 million so partial of interest was not taxable. I logged in TT web version to schedule a free CPA call back. I received a call back in about 10 mins and he solved my problem.
To solve this by editing California state tax item by item, go to Mortgage Interest Adjustment and fill out the 2019 Ending Blanace to be 0 for the old loan.
Hope it helps.
