@TaxQuestion99 , from your post I am assuming that you have need to file at least two different state returns -- a Resident State ( CA?) and a Non-Resident State (?).
In such a case because your Resident State filing is on world income ; Non-Resident State only on in-state income; your Resident State would need to know why / which state is it giving credit for. Thus for your resident state you will need to file State return and attach Federal and the Non-Resident State returns.
Does this make sense ? Or did I read your post wrong ?
