Business & farm

Yes, I have to file a return due to other income.  But where do I document the self-employment amount less than $400? If it's on Schedule C, I'm documenting income on a form I supposedly don't need to file.  Let me also point out that TurboTax charges me $50 to include that form (preparing it as a business return), and this is more than my self-employment income for last year.  Thank you.
