Upon checking your account, I see that you are far from reaching your quota limit?
Regarding your question, if you are referring to free up space of the "Upload Space", you can do that by deleting the submissions that has file attachments on them.
1. Choose the Form and click "Submissions"
2. In my Submissions where I have attached files, like images, you can delete them here. But please do take note that we recommend that you back up or download these attachments first, you won't be able to retrieve deleted uploads.
For the actual submission limits/quota, you cannot free up space on them by deleting the submissions.
I hope this helps. Let me know if I missed the actual concern that you are pointing or if I misunderstood your question.
We'll wait for your response.
