Why can't I efile amended California return?

Previously, I managed to efile both my federal and California returns just fine. Today, I tried to amend them. I made it to the final step of submitting them. But while I was allowed to efile the federal amended return, the TurboTax system says I need to print and mail the California amended return.

I checked the California Franchise Tax Board website and it specifically says submitting amended returns online is allowed. So why can't I efile?

Thank you
