Make sure you put the exact total income on your jointly filed return in question 19a(bc). (So not as suggested above just your wife's part.)
The income from just your wife goes in where they ask for current individual income and if you are not using your income that same number will also be the total household income. (So don't list your income at any of the household member spaces, since you don't use it to qualify, but DO include it in 19abc because that number needs to match your joint return.)
Also include all W2's, including yours, with the tax transcript/return. I've read recent rfe's for not including a W2 from a spouse who was not used to qualify.
