Starting at a community college can have many benefits! It can be a great way to explore different majors and get an understanding of college coursework. If you are looking to attend an Ivy League school after community college, I would recommend reaching out to counselors at both institutions to get a feel for the transfer process. Speaking with advisors at both the community college you are attending and the college you wish to transfer to can help you to gain more knowledge regarding applications, grades, and other procedures related to transfer admissions.
I would also recommend getting involved in activities at your community college and looking for internship opportunities in the field you would like to pursue. Experiences outside of academics can help to boost your college applications.
I hope this helps! Wishing you the best of luck in your future endeavors!
