As a representative of a direct selling company, you are a self-employed entrepreneur. All activity related to this business is reported on Schedule C under Wages & Income | Business Items (or Business | Business Income & Expenses in Home & Business).
You would need to report that income using the directions in the answer below. I have also added some additional information on how to enter expenses and inventory for that business.
ENTERING INCOME NOT ON 1099
Since you didn't receive a Form 1099-Misc, you don't enter your income as 1099-Misc income - the data entry is different.
Type Schedule C in the Search box at the top right of your screen and hit Enter
Select the Jump to blue link
You will then select "Edit" beside your business and walk through the questions until you get to the "Let's get income for XXX" screen.
You will then want to select "Additional Income" (click on screenshots attached) and Continue. This will take you to where you can enter any cash, personal checks or credit card payments (Form 1099-K) related to your self-employment. You may be asked some general questions about your business.
ENTERING EXPENSES
The easiest way to to find Schedule C in TurboTax is to use the Search box at the top right side of the TurboTax header. Enter "schedule c", hit Enter, then click "jump to schedule c". This will take you directly to the start of this section.
You may be asked for a Business Code: most direct sales representatives use business code 454390 (Other direct selling establishments) and use the Cash Method.
If the merchandise you purchased is for resale, it is considered Inventory. If you just started your business this year, your beginning inventory is $0 and the ending inventory is the cost of the products that you still have (did not sell). "Tell Us the Cost of Your Goods" should be the amount you paid to purchase the items from the company. If you used any products for yourself, you will enter than information as well (these expenditures are NOT deductible expenses).
If the items you purchased were used for advertising (not resale), you would include the amount you didn't use yourself under Other Common Business Expenses | Advertising. If you had product that was consumed for demonstration purposes, that amount would be entered under Supplies.
You may claim a Home Office Deduction if you use a dedicated space in your home to store inventory and conduct business. The rules are very specific, so be sure to answer all questions as accurately as possible.
You may also claim Vehicle Expenses for mileage directly related to your business.
Sales taxes paid and collected are reported to your State Tax Office, and are deductible business expenses on your income tax return.
