How to divide interest income between 1040 and 1041 in year of death

Revocable trust grantor passed in 2023.  How is interest income divided between individual's 1040 and trust 1041 returns.  Must income be allocated to individuals 1040 if earned but not paid prior to death?  Likewise must income earned after death be reported on 1041?  Cash or accrual accounting?  1099-INT reports income for the entire year assigned to either the grantor's SSN or trust EIN.  Neither allocate.  Can/should income paid after death be reported on 1041?
