Hi Reilly13,
Thanks for coming to Apple Support Communities for help today.
It sounds like you are in the right spot, but you did not mention entering your Apple ID password or device passcode as mentioned here: How to erase all content and settings. Did you complete this step?
If you have a restrictions on your iPad or a managed profile from work or school, you could be prevented from erasing the iPad.
These articles can explain both further.
- Use parental controls on your child's iPhone, iPad, and iPod touch
- Install or remove configuration profiles on iPhone
If that doesn't explain the issue, then let us know further details.
Have a fantastic day!
