I don't understand if "operation of this business" means the company I am working for or if my self employment is considered a business?
An independent contractor by definition is actively participating in the operation of the business.
The "business" being referred to here is YOUR business which is providing services to some other business (the online company in this case).
You'll just need to get used to the idea that the work you do as an independent contractor is a "business" in the eyes of the IRS.
