Is it possible to accidentally catch a turtle? And what to do if I do

I recently started fishing in a creek behind my house, I fished as a kid but it's been years and only ever salt water so this wasn't an issue. Turtles keep coming for my bait, red ears mostly but also soft shells. I use smaller hooks since im only trying to catch sunfish and bluegill, and the turtles keep going for it. Would it be possible they could hook themselves? And what should I do if they do? (Important note I fish on a bridge because theres snake holes on the edge of the creek, so I'd have to pull the turtle out of the water to unhook it. Would that hurt it?) Picture attached is the hooks I use
