It's not April so I shouldn't be too late to answer this question. "Self-employed" is not a type of business. We need to know if you own a C-Corp, S-Corp, LLC, sole proprietorship, or a partnership. I'm assuming you earned that money without having a formal business establishment. If that's the case, then you still need to fill out Form 1040 (Section C) and Schedule SE for your federal taxes. The IRS has an entire section on their website that covers this information.i'm self employed
