1. In TurboTax, open your return
2. In the left-hand column, locate Tax Tools, click on the drop-down arrow then click on Tools
3. On the Tools Center  page, click on Delete a form 
4. A list of forms will appear. Locate the Home Mortgage Interest Worksheet and click Delete next to it.
5. On the next screen, click Delete Form
