Episode Morty's Mind Blowers suggests that Rick and Morty might have left this dimension when Morty "fucked" with Squirrels though it is unknown of the validity of this memory of Morty's.
Being too lazy to change things back to normal, he just traveled to an alternate dimension where his counterpart did fix it and was also conveniently killed by a failed experiment alongside Morty. When they arrived, they took the dead bodies of that dimension's versions of themselves, buried them in the backyard, and lived out there. It is possible though unconfirmed that, after Morty 'fucked with squirrels', Morty and Rick had to leave for yet another dimension. If this did happen, it presumably did sometime after Pickle Rick where he tells Jaguar he abandoned one of his infinite daughters and 'Morty's Mind Blowers'.
The name of their current dimension is currently unknown.
It is possible but left ambiguuous that, after the events of "Pickle Rick", Morty and Rick started living in a different dimension.
