How do I change the self employed? I was not self employed for 2021 year

If you had self-employment income in the prior year, it would have been carried over to this year's return. You can delete this from your return. 

To delete, please follow the instructions below:

1. Search for Schedule C with the magnifying glass tool on the top of the page.
2. Select 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.
6. Click on Tools. 
7. Click on Delete a Form. 
8. Scroll down to your Schedule C and click Delete. 

Then, you can downgrade by clearing and starting over (this will erase all the info you’ve entered in your return so far).

Keep in mind: You won't be able to do this if you've already submitted payment or deducted the TurboTax fee from your refund.
