How to Commit project to Github to Organization

I want to commit to my Team the project we're working on to make things much much easier, but I couldn't find how. When I use my account to commit, it creates a new repo without asking me where to put it. I tried to put as name NameOfOrganization/NameOfProject but it didn't work. Does anyone knows?
Also sorry if it's obvious but I'm new to IntelliJ IDEA and Github.
