If for any reason you need to delete one of your forms from the Forms app, the process is simple.
First, head into the Forms app. Then, make sure you’re on the My Forms tab.
Locate the form you wish to delete in the table on this page. Hover over the form you wish to delete until the blue gear icon appears. Click on this icon, then, click Delete.
A confirmation menu will appear asking if you truly wish to delete the form. Important Note - deleting a form will delete all of your form submissions. For this reason, you’ll notice that this menu also has an Export Submissions, so that you can quickly download this information before proceeding.
If necessary, click Export Submissions to download the CSV file. Then, click Delete.
A confirmation will appear at the bottom of the page confirming that the deletion was successful.
