Advice plssss🙏😘

I'm in my early 20's, graduated college and working 2 jobs rn, one full time one part time. I have $12,000 saved up and am living at home helping my parents with some bills while saving. I have an old old car that's currently in the 200,000 mile range, which I'm scared will break down on me anyday 😭 I make about $1400 ish a month after taxes..I know not alot. And I paid off $6000 in student loans with just another $6000 left, but thanks to covid no interest is being added on yet.

Pls help give me advice if I am in a good financial place at my age and how to better it, i.e investing or anything bc the money is just sitting in my savings rn and I feel like I'm not doing enough 😩😭
