Taxable Military Income

Question: I-864 Affidavit of Support total income question?
Hello, everyone!
Here is the deal. I sponsor my alien wife for a greencard. I`m in a military, and my last year taxable income is only $11,000. I was deployed so i get nontaxable peace for that, but however it is not shown on tax return, only on my w-2. plus i get howsing allowence, witch is in my paycheck every month but not on w-2.... So, I`m confused, which amount should I put as a total income????
Also, I separated from the military, actually, and got a new job. meet the requarements but work there for less then 60 days so far.... is a copy of paycheck gonna work here for USCIS???
Answer: the key here is making enough to be above the poverty guidelines as required. go here
