dhffkjadhsfkaj when i click on system in settings then backup it just gives me 12 words to write down. if i hit confirm then then another page appears to confirm those 12 words. Am i doing something wrong?
SeedVault backups are encrypted. To restore data from a backup those 12 words are 100% necessary - if they are lost then the backup is permanently useless.
SeedVault thus insists that you record the passphrase words somewhere (at least long enough to re-enter them once) before it will let you choose a backup destination.
If you have not yet done the passphrase verification step it is necessary to do that before continuing. And it is necessary to carefully record the passphrase somewhere that you will be able to find it later (not somewhere on the phone).
