There are many ways to contribute to Open Source projects, depending on the project and what sort of contributions, if any, it is open to. There are financial contributions, bug reports, feedback, a thank you / letting the project maintainers know how you use the project, promoting the project to others, documentation improvements, code improvements, helping with infrastructure, verifying bug reports... its not just coding, and some of these you may be able to do with little or no time involved. All are forms of contribution. Not all Open Source projects are open to all of these, some aren't open to any of them (except perhaps promotion). So it is best to get familiar with the project by checking the site, docs, trackers, etc or maybe reaching out to the maintainers if you still have questions before jumping in.
