There is a bug.
Total outstanding mortgage principal was manually adjusted to below limitations, yet the program persisted with ignoring mortgage interest and forcing a standard deduction. It seems to be an issue when there are multiple debt sources. My work around was to recommence the return and aggregate all debt into one entry.
Regardless, TurboTax is a program that is marketed towards an average Joe who can do his/her own return. It shouldn't require a CPA like myself who actually understands what is being entered and in this case, mortgage interest limitations, to complete the return without issue. Pssst.
