Form 1099-MISC Box 9 reports information rather than income.
Basically, the company reported to the IRS that you purchased over a certain threshold amount of their product(s) for resale. This implies that you will report this activity on Schedule C as income/expenses from self-employment.
If you did re-sell these products for profit, the business activity is reported directly on Schedule C by following the steps here while you are logged into your TurboTax Self Employed account.
