Ah that makes sense, i deleted the record in the tax deduction and only add the property tax i paid along with the interest, it seems the tax deduction was automatically assigned into two different part, one is in the income section, it become -28k, another one is into the Deduction section itself is about 27k. so total i paid property tax and interest about 55k, and ended up splitting into two different sections. and it seems i got more tax cut.
i guess it's the rental income 5k overt the last year was being deducted from the income because 1) it's my own resident house also, 2) compensated by the mortgage interest and property taxes... so basically this 5k rental income was not being taxed eventually.
