Deductions & credits

It's just baffling to me that TT "employee tax experts" are so defensive about this issue.  Diane says thanks for reporting the issue then explains if you just answer the questions correctly TT will come up with the correct answer.  That simply is not true.  I called the TT help line and the first person I spoke with upgraded the call to a CPA in Washington.  He was able to share my screen with me and agreed that THERE IS A BUG.  After we spent about 45 minutes sharing the same screen, and after he recreated the problem on his computer he said he was going to report the issue to management.  It is becoming more and more clear that TT just isn't willing to look at the problem objectively.  I'm not at this time concerned with my personal return as I've manipulated the numbers to arrive at the correct deduction.  I am however concerned that there are probably many users of TT who aren't aware that their deductions regarding refinanced mortgages are not correct.
