Previous to the 2022 Turbotax version, e-filing was not an option for CA form 541. I am having the exact same issue that the OP is having. I assumed since e-file came up as an option, that Turbotax had properly enabled the interface. Looks to me to be a Turbotax software issue and that they tried to add additional functionality without proper testing. Nothing wrong with the return itself or info contained in it as I have filed these by mail for the past eight years with no issues.
