I have a similar issue where I purchased a new home in December 2019 and borrowed $800k but did not sell my prior home until January 2020. TT is adding the full payoff amount of the second home to determine the denominator of the deductible ratio even though I only had that loan for one month in 2020. I haven't determined the best way to "trick" the software into doing it correctly, but this bug almost cost me $2,500. I feel bad for anyone who trusts TT without reviewing the calculations. Seems like I should get a refund of the money I spent for this under their Maximum Refund Guarantee.
