Turbotax 2024 not capping Mortgage Interest on Schedule A- bug?

[mchang999]

It shows 0 interest paid for my mortgage qualifies itemized deduction. This bug leads to a $1660 additional tax payment in our case.  It is crazy!

The mortgage interest section works, but inputting Form 1098 can be tricky. The reason is that the tax laws changed and limited what type interest can be claimed, but Form 1098 wasn't changed to supply all the information needed for the program to make the determination of what interest is allowed and what isn't.

You may wish to revisit that section and go back through the interview questions. 

The program is trying to determine if the loan balance is at or above the limit, and if all the interest was used to purchase, build, or improve the home. 

If the loan is over the limit, and/or a refinance or HELOC loan, the interest may be reduced or disallowed.
