You can delete the submissions with uploads in the View Submission page of your account.
user guide: -How-to-view-Submissions
Use the Delete button on the upper right cornet to delete the existing submission with upload data.
This will clear the current accumulated storage space used by the account.
Please take note: Delete submissions are permanenlty deleted and can no longer be restored.
Make sure to make a backup copy of your submissions before deleting ot avoid loosing the data.
Hope this help. Let us know if you need further assistance.
