You did not move anything - you are just choosing your PSN save data (characters and progress) to play on all platforms.Yo saves are in the cloud, not on the platform. If you ever turn off CrossSave the data will still be on your PS but no longer on Steam.
DLC licenses do not transfer, as they are tied to the platform account you purchased it on.
