Did he die in 2023?  How did you enter or list the husband as part of the household?  He should be listed as Spouse.  Do not pick Widow for her.  Enter her as MARRIED.  Then add him as the spouse.  Then you can pick he was deceased and date.  In the year of death she can still file a Married Joint return with him.  You do a normal married joint return the year he died.
