We can try to find out Community id/owner account from your transactions, yes. Did you use your own account, do you know approximate date of creation? Usually if community creation is successful, you are automatically added as admin and you can see your communities in your profile page. If you don't see it there, perhaps flow broken and setup wasn't finalized meaning community didn't finish setup. We are thinking to implement finalize community setup process next which might help with this kind of situations.
