Deductions & credits

Pardon my ignorance of IRS procedures...I was under the impression that the IRS used computers to match taxpayers returns versus actual 1098s, 1099s and other forms.  If that's the case then combining multiple 1098s into one would seem to be a red flag and potentially lead to some questions from the IRS.  I think what all of us REALLY want is for TurboTax to simply fix the software to mimic what happens on the IRS Pub 936 worksheet to figure deductible mortgage interest expense.  It's so simple even I can do the math!!  

 

TurboTax's big marketing claim is 100% accurate returns and the biggest refund (least amount owed).  The current iteration of their program certainly does neither.
