Liberated != occupied.
You could certainly say that the Baltics were occupied by the USSR, and claim that Poland and Finland were partially occupied by it, though considering the fact that the Polish territory in particular was already disputed pre-war, one could argue that those areas were also 'liberated' by the Soviets (not an argument I agree with, but it can be made). To say that Finland, which lost almost no territory of importance, was "occupied" by the Soviets is laughable; the Finns actually occupied more Soviet territory during the Continuation War than the Soviets ended up occupying in their country, even if one includes the territories taken in the Winter War. Yugoslavia was never occupied by an Allied nation. I do not believe that Albania was either.
But this is beside the point. Obviously, those Axis powers who were defeated - Germany, Italy, Hungary and Romania - were occupied by the Allies to some extent. But Bulgaria didn't even join the Axis until late on and its occupation by the Soviets was fairly friendly, due largely to the fact that the Bulgarians never wanted to fight the USSR, and the Soviets knew it. Italy switched sides, and the North was actually occupied by Germany in response. All the nations listed were either Axis nations or occupied by them; none were Allied nations which were unoccupied by the Axis. It's pretty damn obvious what the OP was going for.
