Deductions & credits

Can someone help me out? In 2019, I moved out of my mom’s house in April. I’ve lived with my boyfriend at his moms ever since. The only bill my mother pays of mine is my phone bill. I pay for my college, car, car insurance, and anything else I want or need. I checked the box also that says “can you be claimed as a dependent?” No one claimed me as a dependent though. What can I do?
