My wife is working with a friend on her business. She got a 1099 NEC. I have filled in the information, and I had to fill out a Schedule C. Two things on this: 1. I don't have a principal business code (required on schedule C). 2. All of the people my wife works with have said they don't use one either. The business owner doesn't even know what it is. They are using TurboTax, and they are putting in the NEC. Am I doing something wrong?
