1041 state question - Dad died while living in Michigan. On the 1041 return the only income is from California rental home. All income was distributed. Do I need to complete Michigan AND California state return?

Hi, my Dad passed away while living in Michigan. He owned a rental home in California.  I've completed the 1041 Federal return and my brother (who lives in Nevada) is the beneficiary of all the income (reported on K-1). Since 100% of the income was distributed do I still need to complete state tax returns?  If so, do I have to complete BOTH Michigan and California? I don't mind doing this, but I hate paying $55 for each state return on Turbotax. :( 

Thanks!
