I have this same issue.
Robinhood issues a 1099-MISC for any free stock you received for referrals in box 4.
The problem is that Turbo Tax assumes any 1099-MISC is a business and then requires me to provide a business license and in my state that will also make the income subject to state excise tax. This doesn't make sense as trading stocks and securities at a personal level isn't considered a business.
