2 Hydrogen atoms and 1 oxygen atoms make clear water. But if you disolve salt into water is it still H2O or is it a new compound entirely?

You know what's there. Most of the water molecules look very much
like they would have if there weren't any salt around. The ones that
are near salt ions are of course somewhat different than they would
have been otherwise. If you put a lot of salt in, all the water
molecules are in somewhat different environments.
Why worry about the words?
