Get your taxes done using TurboTax

Your Google query is assuming you received "commissions" for a W2 job likely in sales.  If your income is from the same business you receive a W2 from, you need to enter the form into TurboTax differently.  If it was self-employment income, you are, in fact, entitled to the QBI deduction.  See Am I considered self-employed? and What self-employed expenses can I deduct? to report your self-employment income.

If you need to change how your 1099-NEC was entered you will need to delete the form and re-enter the information.  To do this in TurboTax Online you can follow these steps:

1. Within your return in TurboTax Online search for Schedule C.
2. Click the Jump to Schedule C link in the search results.
3. If you get to a self-employment summary screen, delete the self-employment income line with the trash can icon.
4. If you get to the question Did you have any self-employment income or expenses? answer No. 
5. Click on Tax Tools on the left side of the screen.
6. Click on Delete a Form. 
7. Scroll down to your Schedule C and Schedule SE and click Delete if they are still there.
8. Search for 1099-NEC and select the Jump to link.
9. Enter your 1099-NEC according to the form you received and click Continue.
10. On the Describe the reason... screen enter "Commission"
11. Choose XXX employer reported this extra money on a 1099-NEC but it should have been reported on a W-2 and click Continue.
