Do I need to file an amended federal tax return if it didn't affect my return at all?

Originally I didn't include $3000 from a 1099-MISC from box 7 (non employee compensation). I used that $3000 to pay a contractor, so it wasn't actually taxable income and it didn't affect my return (federal or state). Turbo Tax even gave me a notification asking if I was sure I needed to file an amended return because there was no difference. I want to make sure I need to send this or not before I mail it. Help!
