It is very funny that I have one loan refinanced twice and transfered four times. I ended up with 6 1098.
My balance of loan never exceed 1.5M but turbotax thinks I have an average balance of 3.57M!!!
If you want to figure out what actually is happening, go to the form view, look for "Deductible Home Mortgage Interest Worksheet" and see how turbo tax is coming up with the number for you. Then you can figure out which box is probably done wrongly. In my case, it looks like turbo tax just can't handle more than 5 1098 forms because the form only has 5 entries for each 1098. The 6th is just missing and ignored for the calculation for my case!!
