Notified on XX June by ZZZ FSDO that the Aircraft X aircraft I was embarked; had a near miss at ZZZ on March XX...ALMOST three months after the supposed incident. Totally unknown; unreported to me or the other pilot who was undergoing his annual 61.58 proficiency check ride in the Eclipse.  I was the PPE (Professional Pilot Examiner) conducting his final maneuver...WHICH was an RNAV to Runway XX circle to land on Runway XY. All proper reports were made on UNICOM; I especially watch the traffic on laptop and on the instruments for other traffic. To my knowledge there was no other traffic in the airport traffic pattern. We circled at 700 feet to the south of the field; turned base leg; and landed. The pilot told me that the FSDO said a Cessna 172 under ATC control now reports a near miss. I am waiting to hear what the ZZZ FSDO has to say on this matter. I suspect it is an ADS-B computer snitch or the ATC controller/other pilot have taken a long time to report the incident...OR Because the FAA folks all work from home this one got put in the 'hold' basket.This could be a dangerous time in space where an aircraft under IFR rules gets turned over to the local frequency (UNICOM) by ATC when he is established on final and does not check in or report his existence to the other traffic ahead in the pattern. It would be most useful if the other pilot writes up his report on this possible incident.
GA pilot examiner reported that FSDO reported a near miss to the them three months after the incident and could not recall any details of it.
