I guess it depends on how you define mass shooting.
According to the Rockefeller Institute for Government (which I had never heard of before) there are about 20 a year, I think as of 2020.
They define a mass shooting an incident of targeted violence carried out by one or more shooters at one or more public or populated locations. Multiple victims (both injuries and fatalities) are associated with the attack, and both the victims and location(s) are chosen either at random or for their symbolic value. The event occurs within a single 24-hour period, though most attacks typically last only a few minutes. The motivation of the shooting must not correlate with gang violence or targeted militant or terroristic activity.

But Gun Violence Archive, a nonprofit research group that tracks shootings and their characteristics in the United States, defines a mass shooting as an incident in which four or more people, excluding the perpetrator(s), are shot in one location at roughly the same time. If you define it this way, the numbers are much higher:
611 mass shootings in 2020 alone.
