To be clear, the schedule C states "An activity qualifies as a business if your primary purpose for engaging in the activity is for income or profit and you are involved in the activity with continuity and regularity. For example, a sporadic activity or a hobby does not qualify as a business. To report income from a nonbusiness activity, see the instructions for Schedule 1"
This tells me that I should not be filing a schedule C but instead should be using line 21 on the schedule 1 form. How do I get TurboTax to do this?
