I still have a few doubts on the use of to/at/in after have been. Thank you for helping me.

1) I haven't gone out for a walk.
I have already been to school (or at school) today.
I haven't been to the cinema yet today.
2) I've already gone shopping online.
I've already done online shopping.
I've had this scooter for three months. (Not: I have gotten this scooter)
3) Katie, who likes rock music, has listened to it since she was twelve.
