You are having the same issue that I am having with my Minnesota return. If you look at the list of supported files for California, you will see that the California Information Worksheet, is not supported for e-file. The state specific Information Worksheet is created as soon as you load the software for the state. Since this is a system generated form, you can not delete it. Here is a link to the supported forms for California.

Only Turbo Tax can fix this and they have not fixed it for Minnesota, so I had to print and mail three tax returns, which takes six weeks to process as opposed to 72 hours for an electronic return.
Next year, I'll be using Tax Act!
