Does it matter which state return I fill out first?

Complete the non-resident state tax return first.  Then the resident tax return.

is there a reason for this?   

Yes. Your resident state will give you a credit, or partial credit, for the tax paid to the non resident state. So, the non resident state tax must be calculated 1st

@bob667 --  There are a few exceptions to the "non-resident return first" rule.  The exceptions all involve California.  Post back if one of the states involved is California.

yes, its California...thank you

@bob667 --  In which state do you live, and in which state do you work?

thank you for your time!  I live and work remotely in Hawaii all of 2019 for a company in Cal

@bob667 -- Are you a W-2 employee, or an independent contractor who receives a 1099-MISC?

i am W2 employee...thank you

California does NOT tax non-resident telecommuters. 

You do not owe California State Income tax on that income. If California tax was withheld, you can file to get that tax refunded. 

<<"i am W2 employee...thank you">>

@bob667 — Then your income is not taxable by California.  But it is fully taxable by your home state of Hawaii.
