W4 Help 18 y/o Dependent with 2 jobs

I am an 18 year old dependent with 2 jobs. One of them is part time for Target, and the other is more of a seasonal/on-demand employee (most of work was during the summer, but there's times now where he asks if I could come in). I am also a full-time student at a community college (unsure if that has any relevance). I was wondering how do I fill out my W-4 for both jobs? Thanks for the help!
