I don't know about the desktop version and the "amended accepted" issue, that's clearly a glitch.
As far as the California e-file, you're getting conflicting messages because the program is not smart, or the programmers did not think of this situation. Any time you select print and mail the software will remind you "Hey, don't you really want to e-file?" because the program wants you to e-file. But if you try it, you will go back to the "It's after 10/15/22" message. You just need to print and mail both returns.
