Deductions & credits

From the letter it does seem like an audit. See picture. Yes, i need to call them to see what is going on.

I recheck the calculation. The TTax worksheet is definitely wrong! but because my loan amount is over 1 mio... TTax software give me an option to over-ride it... and i override it with my own number (which is correct) and therefore... schedule A should be correct. Now, i am not sure what is wrong now... or why my taxes are auditted
