I guess that depends on whether you only travel through time (time vs space), or whether you follow the time-line back (aka. travel through time and space, kinda like both you and I are doing right now).
EDIT: there’s also the reference point, and whether you can bring a physical vessel, or have to possess your younger self.
Back to the Future appears to be using a kind of relative spatial reference point, and you bring your body along the ride.
Contrary, Steins Gate (the part shown in the series) uses a body as reference, and has you “possess” said body. Though it hints that Back to the Future-like travel is also possible.
Not sure if I can name any story where time and space are disconnected.
Larry niven and the known space universe. Doesn’t have time travel, but does have a form of teleportation, where you have to offset the energies for velocity changes between teleport target and teleport destination.

Larry Niven also wrote that hard science fiction is giving the audience enough information for them to tell you it wouldn’t work.
Ahh, enjoyer of time travel movies and anime!
