Issue: If Form 568, Question U(1) is checked No then Schedule K must be attached.

I received this message for my CA state return.  

"Issue: If Form 568, Question U(1) is checked No then Schedule K must be attached."

Historically I have made the same selection on Form 568 U(1), and do not attached a Schedule K.  

However, when I log into Turbotax, my CA state return has been accepted. 

Is there really an error to fix for Question U(1), or is this a glitch ?
