How do you remove a form that shouldnt have been added? Theres a 8915-F attached to my file which should not be there.

Once you are sure you don't need this form, you can delete it. 

If you are using:

• TurboTax Online: see How do I view and delete forms in TurboTax Online?
• TurboTax Desktop:
  1. On the top right, there is a FORMS button.
  2. Click on FORMS.
  3. Locate the form you want to delete.
  4. Click on the form name.
  5. Below the form, bottom left, select DELETE FORM button.
