It keeps telling me my iCloud is full I have no idea what’s in it or how to get to it so I do not want to purchase more when I can’t use what I already have

Turning off iCloud back up is very bad advice.

Icloud give u space

for example: if ur phone lost or not working

u can see ur all data , photo,app,massge in apple web site , it come from icloud all ur data save it there and anythime make back up automatic.

if u dont want , so u change

Go to Settings. Tap the your account at the top of the page. Tap iCloud>Manage Storage.
