Procedure; Environment - Non Weather Related; Human Factors
During a personal flight; I observed smoke associated with a fire; and lots of aerial traffic swarming around that area; according to ADS-B.  The location of the fire was approximately X NM NW of ZZZ1; while I was flying a line between ZZZ and ZZZ1.  My EFB software was not showing a TFR in this location; but did show other TFR's.  The activity suggested there was a TFR; so I adjusted my position to be further east.  Checking the FAA TFR site on my phone upon landing ZZZ1 showed there was a TFR created since my preflight briefing at home; but before entering the area in the flight.  I believe I remained clear; but very close.Contributing factors:TFR was created in that window of time between briefing and flight. In-flight data is relied on for these updates; but the TFR did not post in time. ATC has been difficult to get flight following since Pandemic made them busier; so I stopped trying for short flights.Discovery was recognizing the situation; and corrective action was making room for fire fighting.
Pilot reported flying nearby an area of smoke and was unable to find an associated TFR. After the flight; pilot confirmed a TFR was active but did not post in time on EFB software.
