CA state amended return

[David94]

Hello,

I am e-filing an amended Form 1120S. The federal form was created without any errors, and the "Amended Return" box in item H of Form 1120S is checked. However, when I go to the California state form, the "Amended Return" box is checked in the information worksheet, but an error appears. What is the issue, and how can I fix it?

Thank you for your help in advance.

Have you run through REVIEW to see if you can see more information about the error? 

I know on a CA individual return, you have to uncheck the EF box for the original, and only leave the EF box checked for the amendment, could this be the same problem?
