I finally find the fix or workaround for this. Please go to form review (Ctrl-2) and find the form named - Ded Home Mort. "Override" the numbers you feel wrong including:
1. Months loan outstanding in "Part 1" in page 1
2. num 7 in "Part 1" in page 2 (which is the most important one): please change it to the right average balance.
And if you find the error in the state return, you can delete it in the state, then turbotax will regenerate the new form with the right data.
The trick part: How to "Override" the data in the form?
originally you only can change the cell with yellow color which are the ones you input in the "step by step" mode. for other cell, you can use "override" to change it. How to override? two methods:
move your mouse on the cell you want to change then
1. Ctrl-D
2. right click and choose "override"
