I sent in all 568 from the missing years to FTB. I didn't realize that FTB wasn't receiving eFiled 568 as part of personal return for single member LLC. They also claimed I was late on the LLC $800 recapture tax and fined me for the periods. A year later they found they made a mistake and the recapture tax was actually received on time and they refunded me the fines. A bit stressful initially.
