Inheritance beneficiary tax requirements

I am one of several beneficiaries of a deceased relative living in Washington.  I just received a Schedule K-1 from the Fiduciary that lives in CA.  There are entries in sections 5, 11C, and 14H.  Is this a federal form I need to file or CA state?  I live in TX, where there is no state tax, does that matter?  Not really sure if I am required to file in CA, Federal or not file at all?  Any help would be appreciated!!
