Thanks for the link to the FAQ. As you can imagine, normal customers don't read all the FAQ's before purchasing TurboTax. And TurboTax has an extensive question/answer format to help customers file their taxes, and it can detect a common paying agent, multiple W2's and excess social security taxes paid. So why not alert the customer to options (like form 843)?
As for the CA SDI, the EDD site says it is for those who don't file CA state taxes so I am afraid it will be of no use going down that path.
