I know we CAN Efile a 568 alone without the federal or CA 540, 

Youd have to open the client return in Professional, be sure you've marked the CA  LLC box on either the Sch C or E (whichever type of SMLLC your client has),.

On the fed info worksheet, only mark the CALLC for Efiling, dont mark the federal or CA 540, then when you switch over to the state, choose California LLC.    

That should pull the figures into the 568 and you 'should' be able to Efile and print it alone for just the $43 state PPR fee.
