After adding your domain to your cPanel account, it should've came with a HTML static page. You can save / move that HTML file in a separate folder, delete it from the domain folder, or whatever else you want.
If you're wanting to upload a CMS (like Wordpress.org) to your domain, you can do that with the Installatron. Either that, or downloading the zipped file contents of the CMS you want to work with, and manually uploading it to your domain folder.
If you need further guidance, I recommend calling GoDaddy customer support for hosting. Otherwise, let me know if you have any further questions.
