You need to contact the state department of education in your state and ask how you would establish high school completion through an exam or showing online coursework. Many students who are homeschooled complete their education through correspondence courses and receive a dliploma.

If you studied independently, you may see if you can take an exam at the college level to qualify for entrance. A college counselor would be able to assist you with that information for your area.

Best wishes as you start college next year!
