I Was Given First Offender 11 Years Ago

Eleven years ago when I was 20, I was charged with Transactional card Fraud (felony). Apparently, they sent my court papers to the wrong address, so I was arrested for Failure To Appear. When I finally went to court, I was given First Offender, a fine, and 5yrs probation. I have paid my fine and completed probation and I have never gotten into any trouble since. Recently, I had to go to my local Sheriff's office to get a background check. The only thing on my background check is (Failure To Appear) The background also states that the charged was Dismissed. What I did not see was Transactional Card Fraud. What does this mean? I have two semesters left before I graduate. I know that this is on my record somewhere, I also know that I MUST be honest about my criminal history....have someone been through something similar? Any Advice
