I am having the same problem. I received the email message which showed the following:
What happened
CA_Itemized - We've identified a potential issue in your California return due to an error in our software.
To update your return
Once you've opened your return in TurboTax, the details about what's causing the problem will be displayed.
From there we can walk you through making the updates you need and help you e-file your return.
I ran TurboTax and it installed some updates. Then, I clicked on my return. I did not see any such information about the details or making the updates I need. And running the review again did not show any problems.
I suspect the problem is related to itemized deductions. I used the standard deduction for Federal, but TurboTax wants to itemize deductions for California; I don't know why TurboTax wants to do that.
So, I don't know what is wrong and I don't know how to fix it and I don't know how to refile. My Federal return was accepted a few days ago.
