Senior head of household credit

[PhatFrancis]

I got a prompt from Turbo Tax that I may be eligible to claim the senior household credit ( CA STATE).  But in prior years I have always filed as Married Jointly until the year 2021 when my wife passed away.  This filing year 2023 is the first time I received such prompt .  Please advise
