Yeah, just recalibrate.
Sometimes the way a tire slips on the road surface, or you get a large suspension bounce due to bad road surface, it can trigger a false positive on the TPMS. I have had this a couple times over the years, and a simple recalibration of the TPMS takes care of it.
If the TPMS alerts again shortly after you complete the recalibration (which does take some road driving with these indirect systems) then you might have a defect in a wheel sensor (which is how the vehicle tracks the relative wheel rotations of the tires). Been a small number of these reported, but it is not common. So just pointing this out for completeness in discussion.
