Should I quit my part time job?

I've been working two jobs for awhile now and I'm trying to become financially stable. I'm trying to become debt free. I work part time at a grocery store as a cashier at $12/hour and I only as of this month work 4-9 hours a week since they are scheduling people according to last years sales. I also work doordash full time. My question is should I quit my job at the grocery store or keep it?
