How to I calculate "Inc subj to tax by oth st" on AZ Form 309?

[brorad17]

I'm a resident of CA, I worked in AZ for a few weeks and got a W-2. Now I'm filling out state tax returns in TurboTax and it says "Check This Entry   Form 309 (California): Inc subj to tax by oth st must be entered.  Inc subj to tax by oth st."  I don't know what it's asking for.

You are being asked for the amount of income you earned while working in Arizona.  That income is subject to Arizona income tax.  As a California resident, all income, regardless of where earned, is taxable by California.   You should

prepare your Arizona non-resident return before preparing your California resident return.  California will give you a credit for tax paid to Arizona on your California return.
