I was on a VFR flight. I was following the ZZZ 310 radial inbound and approximately 28 miles from the ZZZ VOR.  My plan was to turn southbound towards my home airport ZZZ1 before approaching the ZZZ area.  I was watching the floors of the Class B as I approached ZZZ; but I inadvertently crossed into the floor airspace. Upon realization of this fact I immediately turned around and descended to clear this airspace.  Not flying during the COVID-19 restrictions made me rusty and behind the airplane.
Pilot reported inadvertently flying into Class Bravo airspace and cited lack of flying during the COVID-19 pandemic as a contributing factor.
