Trying to get a STEM internship or part time summer job. 14 yr M Washington DC area. Recommendations? New and inexperienced with growing up.

I'm 14 year old male and I live in The Northern Virginia/DC area. I am really trying to get ahead and maybe get a job or internship to help me prepare or pay for college. Both parents are in there 50s and are from a different generation. My dad told me to walk into a store and give them my resume, and shake their hand and introduce myself. It failed and the apple store told me to apply online. I know I am Young, but you have to start somewhere. I am really into STEM related activities, and I want to become a software engineer when I grow up. I was wondering if anyone could link me website that would help me find internships or jobs , or even just programs for the STEM field. I really appreciate any help or tips you could give me. You guys are my only hope. Lead me in the right direction!
