It looks like your average loan balance for the year is around $900,000, which means some of your mortgage interest will be non-deductible due to the $750,000 limit. Although some of your interest is older than that and would be eligible for the $1 million limit, the limit is the greater of $750,000 or the outstanding mortgage principal subject to the $1 million limit up to $1 million.
Without seeing your numbers, I can't say for sure if there is a miscalculation, but based on your outstanding mortgage principals, I would expect about 5/6 of the interest you paid to be deductible. That's quick, back of the napkin math. If it is anywhere in that ballpark, everything is probably entered correctly and TurboTax is correctly limiting the interest based on the IRS limits. If it is nowhere near 5/6, we may have to look a little deeper to see what's going on.
