I have X years of experience flying helicopters both IFR and VFR in the area.  I know the area well.  I know the rhythm of sporting TFRs and where to find the information (usually ForeFlight). Unfortunately; COVID in 2020 has effectively eliminated almost all of the normal sporting events.  I actually thought that since fans couldn't go to sporting events that there would not be any active sporting event TFR's at all since they wouldn't meet the people density standard.  Tonight; while en-route to ZZZ1 from ZZZ2; I learned that is not the case.While following my normal routing from ZZZ1 to ZZZ2 following Interstate-number Southbound and asking for a ZZZ transition over the south field to ZZZZZ; I called ZZZ Tower to ask for the transition when the Controller asked me if I knew that I was in a TFR.  I apologized and informed the Controller that I didn't and that I didn't see the TFR on my Garmin GTN nor on ForeFlight.  Another pilot chimed in on freq and also said that he didn't see the TFR.  The Controller simply said copy and gave me the transition without mentioning the issue further.I then saw that I did not have the TFR layer on my iPad (ForeFlight) turned on. As soon as I landed in ZZZ2 I turned on the layer and sure enough there was the TFR.  I must have clipped the edge of it on my track inbound just north of ZZZ.This issue really stems from unacceptable complacency to sporting event TFR's during the COVID year and also the fact that they don't populate to my Garmin GTN via XM like normal TFRs do.  I really wish they would standardize the delivery of TFRs so that we can see then across all services.Regardless; it was unacceptable to not have fully reviewed the flight path for all TFRs prior to departing ZZZ1.  ...a mistake I won't be making again.
