There are a few features like Turn Undead which state:
A turned creature [...] also can’t take reactions. For its action, it can use only the Dash action or try to escape from an effect that prevents it from moving. If there’s nowhere to move, the creature can use the Dodge action.
It seems like this effectively removes a creature's reaction and action, but it never says anything about its bonus action. Does this mean that a creature affected by Turn Undead still has its bonus action available for use?
