The message you posted said "Box 1, 3, OR 8." It doesn't say you have to enter something in all of them. You only report your situation. It sounds like the message is telling you that no interest has been reported, and that you need to make an entry on it in Box 1, 3, OR 8.
Leave any boxes blank that you don't need. Savings bond interest is in Box 3.
It's possible to need more than one box if you have other items to report from that bank. Did you get other bank interest besides the savings bond interest? I won't know if you also received any regular bank interest on your deposit account. Box 1 is usually for interest on a bank checking/savings account, CD, etc.
It says "untitled" because you haven't yet entered the bank name.
