You can add information for your self-employment (your own business) to the Schedule C for your Form 1040 by following the directions below. (Please note: you may decide to upgrade to the Home & Business edition to help you enter all of your business income and expenses)
- Go to Federal Taxes
- Select Wages and Income
- Select I'll choose what I work on if the option is given
- Scroll to the heading Business Items
- Select Start next to Business Income and Expenses (Sch C)
You can walk through the interview to enter your income (including both your 1099-MISC, if any, and other income received) and the expenses related to generating that income.
I've also pasted a FAQ below on what a Schedule C is and how it relates to your business.
