I want to do ALL forms not just 1 form at a time
You can only deleted submissions form by form.
The only way to remove all submissions from several forms at the same time would be to clone each form and then delete all of them.
I would however personally suggest only deleting the submissions from one form at a time to avoid removing anything that you would like to keep.
Do note that once removed it is not possible to restore the data back.
