I am unable to efile a California return. It says that that the efile failed. I need an update to turbotax but when I try to update, it says I have the latest version.

Keep getting the following error after transmitting: FAILED_VALIDATION. There is an update available for your version of TurboTax. Before you can file electronically, you'll need to get this update. To do this, go to the Online menu and select Check for Updates. I do this, and it says I am up to date.

Are you on Windows or Mac?  For Windows see if you need any Windows updates.  Try a couple times, a Windows update might be stuck.  Did you try doing the manual update?

If your program says it's up to date or you can't update it then do the Manual Update for Windows

I am using TurboTax home in business on a Windows 11 machine. The federal form has been e-filed without issue, but the California returned filing brings up the update issue described above.
