Interesting. I've also had problems with my California state return. In my case the return completes ok but I'm unable to go through the process of paying for the filing. I'm told it is not able to verify my card, and when I try entering another card the "continue" box is greyed out. This has gone on for over a week...I've probably spoken to 6 agents and none of them are able to help. Last one said I should go ahead and mail it! Kinda defeats the purpose of using Turbotax. Today the fee went up $5. My federal form was efiled ok. Crazy and very frustrating!
