If you’re looking to add someone to your Fortnite PC account on PlayStation 4, there are a few things you need to do. First, create a new account on the PlayStation 4 system and enter their name into the login screen. Then, open the PlayStation Network app and sign in with that account. Once you’re logged in, go to the “Friends” section and add them as a friend. Finally, open the “Fortnite” menu in your game client and select “Add Friends.”
