Greetings raine112,
Thanks for posting in the Apple Support Communities.
It sounds like you're needing to clear up some storage with Documents & Data on your iPad, right?
If we have that correct, the storage reported here can include files stored within installed apps as well. If you still have the uploaded videos downloaded on your iPad, see if removing the download will clear up this space. For additional information on what the storage categories include, check out the details below. You can also locate more information, here: How to check the storage on your iPhone and iPad - Apple Support
Here's a list of the types of content on your device, and what each type includes:
• Audio: Songs, audio podcasts, audiobooks, voice memos, and ringtones.
• Video: Movies, music videos, and TV shows.
• Photos: Content in your Photo Library, Camera Roll, and Photo Stream.
• Apps: Installed apps. The content of the apps is listed under Documents & Data.
• Books: iBooks books, audio books, and PDF files.
• Documents & Data: Safari Offline Reading List, files stored within installed apps, and app content like contacts, calendars, messages, and emails (and their attachments).
• Other: Settings, Siri voices, system data, and cached files.
In addition, you can try clearing the history and cookies from Safari if you think this may help. For assistance, and more details on this, check out the following link: Clear the history and cookies from Safari on your iPhone, iPad, or iPod touch - Apple Support
We hope that's able to help. If not, include additional details to help us understand what's occurring. Be sure to let us know which steps you've taken as well to allow us to avoid repeating any unnecessary steps.
Have a great day!
