I am a Sole Proprietorship so I don't have a business name so under the business name, what do I put down as my business name: Uber or My Name?
You can create a name for your business if you choose, but since Schedule C flows to your personal return, most people just use their own name and home address.
You are not Uber. You are you. If you don't have any other formal name for your self-employed/independent contractor business, you would indicate to the program to use your regular name and address as your business name
