Self employed

It may be that you have business expenses equal to the income you entered from the Form 1099-NEC. Even if you didn't enter any business expenses, there could be suspended losses carried over from the previous year or depreciation deductions from assets entered in previous years.  

I suggest you edit your business entries and on the screen that says Your (Name of Business) Business, look down the list of expenses and see if there is any amounts showing next to the expense categories. 

Another possibility is that you entered the form 1099-NEC income as Other Income as opposed to self-employment income. You had an option to choose that in the screens after your entered the Form 1099-NEC. You can look on your schedule 1, line 8(z) to see if that is where your income ended up. If so, it would not be considered business income for SEP IRA purposes.

You can view your form 1040 and schedules 1 to 3 while working in the online version of TurboTax by following these steps:

1. Click on Tax Tools in the left menu bar
2. Click on Tools
3. Look under Other Helpful links….
4. Choose View Tax Summary
5. Look in the left menu bar and choose Preview my 1040
6. Scroll down the page to see form 1040 and schedules 1 to 3
