Bonjour Dipika !

Technically, this sentence "J'y peux venir ce soir" is correct to say "I can come there tonight".
However, no one French would actually use this formulation.

We'd rather say:
Je peux venir ce soir.   or
Je peux venir ici (here)/là (there)/là-bas (over there) ce soir.

I hope that's helpful!
