You will have to delete the forms and worksheets that are making the program ask you small-business related questions. This would include any Schedule C used in prior years and Form 8995 Qualified Business Income Deduction.

After deleting these forms and worksheets, log out of the program. When you log back in, use the Delete a Form tool (List of Forms in My Return) to confirm these worksheets and statements have been removed from your return.
Why does this happen? When you transfer the information from your prior year return, the program automatically includes certain forms in the current year - to make sure you don't forget to update those forms. If a form is no longer required (e.g. K-1s, Schedule C), you have to delete them from the current year.
