You may have to download and install the GitHub Desktop which can be found here https://desktop.github.com/ and/or the official Git client found here https://git-scm.com/download/.
Once you get either/both of those setup and connecting to your GitHub repositories. You may need to configure Two Factor authentication or something along those lines.
After all of that try IntelliJ and GitHub once again, however you may want to start with a fresh project and choose VCS -> Import into Version Control -> Share On GitHub from the menus.
