Deductions & credits

This calculation by Turbo tax is wrong. The algorithm of TT is incorrect. If I don't add second home my interest calculated is 750/765 *21000 which 20400.

So TT is penalizing me for having a second home for which I paid more interest. 

How come my actual interest goes down when I actually paid much more interest. 

This is definitely a big where TT does not handle 2 homes correctly. 

I had first house for whole year. Second house was bought in November. First house was pending sale and was actually sold in January. 

 

 

I am sure that IRS cannot do such injustice and definitely handles it better. That's why I calculated interest based on months where I claim 11 months for 1st house and 12th month for 2nd house.
