Are you doing a 1040X? If so Check the box for Amending federal return, the put 1 in the next box and select the dropdown for CA. If your not amending federal don't check the box, but that next 1 to amend state is probably what is missing.
Thanks for the quick response. I did check the box and input 1 into the below box, but there is no dropdown where I can select CA. And I can see that the CA schedule x field is being used on the left.
See my snip-it.
