If you are only reporting income on a Form 1099-NEC or 1099-MISC, and you have no associated expenses, you can use Deluxe. If you are reporting income that is not on a 1099-NEC or 1099-MISC, or if you have expenses to deduct, you have to use Premium.
If you use the CD/Download TurboTax software you can use any edition, but Home & Business will give you a more detailed interview and more guidance and help for entering your business or self-employment income.
To begin entering your business or self-employment income in Online Premium or in the CD/Download software, in the Search box type "schedule c" (without the quotes), then click the link that says "jump to schedule c."
