This is very easy to miss. In the California interview, on the page "Business Summary", (and you get there by clicking on the "Start" button next to "Business Summary" on the "Uncommon Income and Other California Adjustments" page), there's a "Note" that reads "if any of these businesses are a Single Member LLC for California, select edit next to that business."
Selecting "Edit" and confirming that the business is a Single Member LLC brings up a page titled "California requires that you e-file form 568" and that's where you are told that you can e-file this form if you download TurboTax Business, and you're also told that "California allows some people to print and mail form 568, with a link to the FTB's site. Then you are presented with the various pages of form 568 to fill out. There's really no "interview" per se, you are simply filling out the form in the same fashion you would fill out a paper form 568.
Having worked through the various pages of form 568 you ultimately come to a page with a "Print Form 568" button on it.
