(Using TT Home & Business 2024 Mac) I want to efile CA form 568 for my SMLLC. It is forcing me to click the box to file by paper; why? How can I efile this in TurboTax?

I have only one single member LLC; the 'walk me through it' guide indicated that I would be eligible to efile it. But when I finish up, it says there's an error, brings up 568 in forms mode, and says I need to check the box at the bottom that indicates "If prompted to check this box, TurboTax cannot efile". It does not say why I can't efile -- is there a way to fix this?
