Do we know what the actual land of Antarctica would look like if all the ice was gone?

Yes we do

This map was created by using a combination of radar echo data, satellite data, and existing maps of ice free areas of Antarctica.

Red is peaks and green is land that’s just above the current average sea level. Light blue is what would be shallow seas.

As you can see, Antarctica is mostly a continental shelf with an archipelago of islands that rise above sea level. The water between the islands is relatively shallow, so it’s a bit like the shelf New Zealand sits on.
