Prize winnings without 1099

No, that is not correct. 

If you accidently created a schedule C, you will need to delete it and the related 1099-MISC form. Follow these instructions:

• With your return open, search for this exact phrase: sch c (include the parentheses) and then click the "Jump to" link in the search results.
• Answer Yes when asked if you had (or want to work on) business income and expenses for 2015.
• That's right – you'll need to answer Yes, even though it doesn't make sense.
• When you get to the Business info or Business Summary screen, click Delete next to the defunct business.
  
• Answer Yes to confirm the removal of all business-related forms.
• In the upper right corner, click My Account > Tools.
• In the pop-up window, select Delete a form.
• Click Delete next to the form or schedule and follow the instructions to remove the form/schedule.
• Delete your 1099Misc form (it may have been deleted when you deleted the Schedule C).

To enter your Prize winnings so it is not taxed as wages (self-employment income):

• Type other taxable income in the search bar
• Click on Jump to other taxable income
• At the Other Wages Received screen, answer NO and continue
• Scroll down to Other reportable income, click Start/Update
• Click YES at Any Other Taxable Income?
• Enter Prize Winnings, the amount and continue.
• The amount should appear on your Form 1040, line 21.
