I made a mistake and hit business for a 1099 misc, how do I delete the business section of my tax return

To delete the Schedule C in TurboTax Online, Please go to:

• Federal Taxes
• Wages & Income
• Business Items
• Business Income and Expenses (Sch C)
• Start or Revisit
  

You will get to Business Summary screen that lists the business and the option to delete is next to each business listed on the return.

You could also just delete the form itself this way:

• Select My Account (After you have gone past the orange, ''Take me to my return'' button)
• Tools
• Delete a Form

 Then choose to delete the Schedule C from there.
