how do i clear the upload space?

I have deleted all submissions, but it still says that I am out of upload space. I can't seem to find another area where the uploads are so that I can clear it out. Can you please help me clear it out so that I can get my form back up?

I tried accessing your form but cannot replicate the issue. It is working now as expected.

Could you please try accessing it again?

Let us know if it still persists.
