What Simon has stated with regards to the new I-134 is NOT applicable to DV selectees processing via AOS, that is only relevant to folks processing CP. USCIS did not say anything about interview needing to happen before June 27th, USCIS says they will accept old I-134 filed before June 27th. It is important to differentiate between what Simon says on his blog which is largely addressing folks filing CP and what USCIS which is the final authority of AOS cases says.
You have no personal income of your own to list on the new I-134 IMO, the income is under your husband's name. You have no W-2 or tax transcript to back up the claim of your husband's income as your personal income, not even the $5000 you get per his I-20, that is a stipend not an income. You are not employed by your husband's employer, or can you husband's employer provide you with a verification of employment letter? I don't think so.
