Currently a regional captain- back when I was an FO about 3 years ago, we were descending on a STAR when I accidentally put the wrong bottom altitude, causing us to descend 1k lower than published. Approach quickly queried us as we were descending and I immediately corrected. Landed into OMA and got the dreaded phone number on the ground for a possible pilot deviation. Filed an ASAP, had a phone call with the committee and they said that it was all handled via ASAP, no further actions taken, no FAA action either to my knowledge of the events since it was a while ago. I recently decided to apply at a fractional- and it asks a few questions regarding pilot history- to include “was I ever a member of a crew that was under investigation or received a violation by the FAA” as well as “have I ever been involved in any aircraft incidents or mishaps either reported or unreported?”

I want to answer honestly of course, but I do not want to answer yes when in reality it was no and hurt my chances. Wanted some other opinions on what to put since it was all via ASAP. Nothing on PRD at all as well
