Narrative: I accepted a flight request for a patient transfer flight to ZZZ. I completed my preflight planning which included a review of possible sporting event TFRs on my route of flight; I saw none. I departed from our base and flew to the hospital. We then loaded the patient and we departed for ZZZ. I began my decent from cruise down to approximately 500 feet AGL while about 5 miles from the hospital; we landed on top of the hospital without incident.We were at the hospital for about 35 minutes; and I then began my flight planning for the leg home. I opened my FOREFLIGHT app to double check Weather on my phone and immediately saw that we were inside a TFR. It said the TFR was active although it listed a 'Warning;' 'that the start time for this event could not be determined.' It was a TFR for a sporting event. I am unsure whether or not this TFR was Active when we entered the Vicinity of ZZZ and landed at the hospital. I also began to wonder why No information on my G500 or G650 with TFR warnings (turned On) had Not activated. I turned my avionics On while on the roof and again there was NO red circle or any indication of a TFR being displayed.I called ZZZ Controllers and told them I was located on top of at ZZZ Hospital roof as a medical helicopter and am requesting clearance to depart the TFR with a squawk code back enroute to ZZZ1. The Controller gave me a squawk code and said I could depart at any time and simply squawk 1200 when I was well clear of the TFR. I programmed my transponder with the code and we departed ZZZ back to ZZZ1.Later the same day we had another flight request back to the hospital in ZZZ; I contacted ZZZ Controllers and was again given a squawk code; we entered and exited the TFR without incident. It is also noteworthy that when I departed the hospital for the second time that the TFR was showing ACTIVE on FOREFLIGHT and ZZZ1 Controllers said it was no longer active. And again; no indication of a TFR on my G500 or G650.In the future I will be more diligent during my preflight planning and multiple Legs and stops to check Multiple sources to confirm if a TFR is on my route of Flight. I also think with COVID-19 game day schedules are more fluid and subject to change and this has made the preflight planning more challenging in determining whether or not a TFR is active or not.




Synopsis: Helicopter Pilot reported a possible sporting event TFR violation. Pilot states the times of these active TFRs appear to change with little notice because COVID-19 is causing many changes to event schedules.
