I'm not recommending this method for all bikes, but did you saw a slit down all the way along the seatpost?
I'd say I got lucky in that the aluminium lug connecting the carbon tubes was strong and didn't get deformed. I think yours is slightly deformed?
What worked for me was cutting all the way down along the seatpost as evenly as possible with only a microscopic sliver of aluminium connecting the strips of seatpost made by the slits.
If you have reduced the diameter of the tube, a long nose pliers might give you the force u need to pull it out. But what do I know?
