I did not input any Sale of business property. But my income and expenses keep showing me -8334 dollars in expense

Are you seeing $8,334 in total expenses, or that amount related to the sale of business property specifically?

Under the Federal menu, choose Income & Expenses. If you have self-employment income and expenses, you can choose Edit/Add. From there, you will see the business. Click Edit. You will see the various expense categories and can click the trash can icon to the right of them to delete.

Or, if you did not have self-employment income and expenses, in the Wages & Income menu, you may see the Sale of Business Property. If you click Edit to the right, you should see the transaction listed. You can click the trash can icon to delete.
