All the IDEs *way too many*

Now if you click into this it should bring you to something like this.

Within here you should find IntelliJ Idea Ultimate and a number of other IDEs for different Programming Languages. Now once you haven't made any project before you can double-click on IntelliJ Idea Ultimate which should bring you to a menu like this.
