How do I link my 1099-MISC to a business (Schedule C)?
Menu Path: Income > Business / Rental Income > Business Income (Schedule C)
Depending on the type of income it's reporting, a 1099-MISC may need to be linked to a business (Schedule C), rental or royalty (Schedule E), farm (Schedule F), farm rental (Form 4835), or as other income (Schedule 1).
You can link your 1099-MISC to a business (Schedule C) on the Link 1099-NEC or 1099-MISC screen of your Schedule C.
On that screen you'll see a list of unlinked 1099-MISCs. Check the box to link the 1099-MISC to the business.
If you need to enter a 1099-MISC for your business, answer Yes to the question on the Link 1099-NEC or 1099-MISC screen that asks if you received a 1099-MISC for your business.
