Fill out the US immigration DS-260 form, why can't I add another one? How to add another person?

What kind of immigrant visa are you? CR 1? F2A? F3,F4? For the first two cases, all beneficiaries are independent cases. After logging into CEAC website with the beneficiary's own case number, I filled out the form. I'm not very clear about F3 and F4. I forgot what to fill in the 260 form. . . It stands to reason that after logging in to the CEAC website, there should be information about each beneficiary. If it really doesn't work, you can contact NVC.
