I have two mortgages and appropriately did the manual calculation to factor in the mortgage interest limits. However, my itemized deduction deductible interest is almost 15K above what I entered giving me a significant refund. All of this happened from one log in, log out, then log back in. I have been waiting for the software to correct, have deleted the mortgages and reentered them manually and the difference still there - is there a BUG? not sure how to get to the turbotax support to verify.
