The annuity benefits belong to the designated beneficiary. You will have no rights to the annuity benefits even if the designated beneficiary dies and the claim has not been paid out. In that case, the claim will become an asset of the designated beneficiary's estate.
At death of the annuitant, an annuity passes to the named beneficiary of the annuity. If there is no beneficiary designation, it passes to the estate unless there is default language in the annuity contract that says something else.
I'm not sure I understand your question. If you and your brother are beneficiaries and have filled out the claim forms and provided a death certificate, you should have received the check. There is something in your fact pattern I don't understand.
