When a process form is no longer needed, the form can either be trashed or archived. For trashing a form this could be due to accidental creation, outdated information, or a new form has been created to replace the existing one. A trashed form is deleted permanently, it is recommended to archive a form over trashing for historical purposes. 

Top menu >> Processes >> Select process >> Select form 

When in the form click More at the top. 

In the More menu, click Trash

The form has now been trashed. If you accidentally delete the wrong form, you have 7 days to restore it from the trash before it is permanently deleted.
