How can I prevent a Schedule C from being generated?

I have 1099-misc for Tribal Membership Distribution and the amount was listed in box 3. I have no business and I did nothing for this income other than being a Indian. IRS says all I have to do is enter the amount in line 21 of my 1040. Turbo Tax enters the amount in line 21 but then creates a Schedule C for Businesses.  How do I prevent a Sched C from being generated? No matter how I answer the questions, it always generates a Sched C.
