how do I get out of my business when I don't have one

If you were self-employed last tax year, it will carry over to this year. In order to delete this, you would have to delete the Schedule C (if you reported income that was not on a 1099-MISC). 

1. Open your return in TurboTax.
2. Search for Schedule C with the magnifying glass tool on the top of the page.
3. Select the Jump to Schedule C link in the search results.
4. If you get to a self-employment summary screen, delete the self-employment income line with the trash can icon.
5. If you get to the question Did you have any self-employment income or expenses? answer No. 
6. Click on Tools.
7. Click on Delete a Form. 
8. Scroll down to your forms and look for forms you need to remove and click Delete.
