Two state Tax returns

[sfowjr66]

In 2018 I lived the entire 12 months in AZ. In addition to my 1040 I also filed return with AZ. I reported and was taxed on my salary as well as my investment income.  But Vanguard send my 1099 Div to my parent's house in CA.  I reported all my Vang invest income on my AZ return.  Now I receive letter from FTB in CA telling me that I need to file a tax return in CA for the investment income.  I think they received copy of the 1099-Div from Vanguard since it went to my parents home in CA.  I am 35 and not a dependent.  Advice please? Seems to me I was properly taxed by AZ for all of my income including the investment income.

Thank you.

You will have to contact the California FTB to find out what information you will have to provide to them to clear the discrepancy.  Most likely, a copy of the 2018 resident income tax return will be sufficient.
