How can I get the final court disposition when the citation happened when I was 16-17 years old at the time?

I am trying to get approval for global entry (pre TSA check for traveling). Long story short, my background show 1 citation back in 07/2001. I was 17 at the time. The global entry agency didn't know what it is for but I was positive it was for shoplifting at the time. I remember I was fingerprinted and paid the fine directly to the store $500. Is that a civil charge? Anyway, the global entry agency is asking for the final court disposition. Is there even a court disposition even if I never went to court and just paid the fine? If there is such record, will the record be at juvenile court? Is there a way for them to show that it was settled? I called the police station where I was booked but they passed me onto the hall of record. I called the court house and they can't find anything- told me to call juvenile court. I can't get through. No one can give me a straight answer. Do you think that the record is sealed and they can't give me much info?
