Thank you!

You have more than 100MB of files in your account. You will have to delete them to free up the file storage space. I see you have a few forms in the trash folder. The data in trashed forms are still counted. You will have to purge the forms to restore. 

To delete submissions: https://www.jotform.com/help/377-How-to-Delete-Form-Submission-Data.

Please make sure to have a backup of the data before deleting. Once deleted, there is no option you can recover them later.
