TurboTax is correct. If you're an Independent Contractor the IRS says you're the owner of your business.
You may not think of yourself as running a business, but you’re considered self-employed if you engage in business-like activities. In TurboTax:
- Enter your Name as the business name,
- Enter your address as the Business Address and,
- Click on NO when asked if you have an Employer Identification Number.
You are self-employed if you’re an individual who:
- is the sole proprietor of an unincorporated business
- works as an independent contractor, consultant or freelancer
- is a member of a business partnership
- owns or is part of a limited liability company (LLC)
- earns income through investments
- earns income through rental property.
