They are both reptiles
Turtles living today are not the same species living at the time of the existence of dinosaurs. And today, BIRDS, are the form in which dinosaurs survived.
No birds are.
Dinosaurs
Turtles were cold blooded and smaller than dinosaurs. Dinosaurs were much larger than turtles and had a higher metabolism, which caused the to starve much faster than turtles. Turtles could survive on the tiny scraps of food they could find until plants began growing again.
Animals that are definitely turtles are found from the later Jurassic period, with some almost-turtles like Proganochys found in the late Triassic. The first dinosaurs are found in the early Triassic. So far, fossil evidence suggests that turtle-like possible ancestors with partial shells predate dinosaurs, but dinosaurs predate true turtles.
Dinosaurs and turtles share the Class Reptilia; but that's about it. Turtles (though not necessarily red sliders) preceded the dinosaurs and survived them. (Which is not to call the dinosaurs unsuccessful; they lived large while turtles kept - literally - a low profile.)
Both are vertebrates.
