Someone walk me through seeing blocked numbers on iphone?

Quick one - if you're getting spam calls that never show up in that list, it might be Silence Unknown Callers rather than a block. That's under Phone too, and it sends anyone not in your contacts straight to voicemail without blocking them.

Settings, scroll down to Phone, then Blocked Contacts, and the full list is sitting there. On newer iOS it moved into the Apps section first and then Phone, which is why half the guides send you somewhere that no longer exists. It's one shared list, so anything blocked from Messages or FaceTime turns up in the same place. Tap Edit, or swipe a row left, to undo one. Numbers that were never saved as contacts just show as bare digits.
