Obscure history

Hello all again and thanks for the help in the past.
New question today as ive looked almost everywhere else for the answer.

Im pretty sure I got a non movement violation driving back in 2018 and was told it wouldnt go on my record. What it was for? Exactly when or where? I couldnt tell you. Ive called insurance, looked up Pilot Records Database (PRD)on the faa, and requested records from the DMV. All come up with NOTHING. Im happy to bring it up in an interview but if I cant find any trace of it or accurately describe it in airline apps, should i mention it in my airline apps or wait for the interview and theyll probably find nothing anyways in the pria?
Thanks in advance!

Cameron,

Non moving violations are not an issue as long as they’re not drug or alcohol related. No need to report it.
