Please Help

So I have an issue that I need help with asap... I filled my taxes with the same tax preparer I have used for the past 5 to 6 yrs. After 7 yrs on the housing waitlist I finally receive the housing assistance I prayed for but now I may lose my housing due to tax issues... My AGI does not match my earned income.. I only work part time and only made 7 plus thousand a yr..but my AGI says 16...I no longer have the same tax guy but now Im stuck with trying to prove I didnt make that much.. So question is how can I get my AGI to match my earned income after I already filed and was not rejected.
