Most OSS contributions come out of scratching your own itch. Pick a project you're actively using. You'll discover features you wish it had, or bugs that creep up. Add the feature, fix the bug, add some documentation for a feature you found confusing. Soon enough this will become just the way you interact with the OSS community. Welcome! :)
