So I did some digging around found out alot of people has been getting this kind of deal. I went back to the bank and sure enough they were fake. The bank gave the checks back to me and i,m going to report this to the FBI

I just wanted to say watch out if this happens to you

PS if you cash the checks you will have to pay back all the money and be charged a felony
