I don't think Bocsánat oda means anything! I wonder if you might have misheard someone saying a sentence beginning with Bocsánatot, a ... or something similar.
Bocsánat by itself can be used as a fixed expression to mean, "Excuse me" or "I'm sorry". But bocsánat is a noun meaning "pardon" or "forgiveness" and you can also use it in longer constructions like, Bocsánatot kérek which means literally, "I ask for [your] forgiveness." It acquires the accusative ending -ot since it's the object of the sentence.
And in a rapidly spoken sentence, bocsánatot might sound like "Bocsánat oda"
No, you need the directed form oda which means "TO there."
oda - to there
ott - there, at that place
onnan - from there
Menj oda! - go (to) there
Jól van, most ott vagy. - OK, now you are there.
Menj el onnan! - Go away from there!
