Zaren: How long you have been to USA and what is your future plan? If planing for GC you need to do your own homework first. I mean as that dude suggested , get a 1040 form and instruction , spend your weekend on it. Do not rely on us  specially on Tax  matter and most tax specialist will not spend their time suggesting on sajha blog.
Nothing is wrong on most tax software but something on your head. If you have not  complicated tax filing , the results from most online tax software will give you the almost the same result. In your case , you worked two place that is all, If you see wrong , the instruction book will show you how to calculate tax libility. Get the answer by yourself and still not satisfied, give us figure we will show you step by step , why you are paying that much.

Now you are asking for nothing because you have  not done  your own home work and we can not make you literate  on tax matter overnight and  that is via sajha Kurakani.

Sorry bro; Sarcasm is one of the sevices we provide free here in Sajha.
ज्यास्ती कमाओगे तो ज्यास्ती हि तिरोगे ना भैये. Even a 12 dollar interest may give you different tax liability.

Did anybody suggested to exclude it or you trying to be an wise ass?
