Ours was rejected with the exact same error, even though I've checked it against previous years that were accepted without issue.
I'm wondering: Do you have an entry on line 8z ("Other Income: List type and amount") of Section B of Schedule CA (540): California Adjustments? We do, but TurboTax is leaving the description of that addition blank, even though it's supposed to either state what the addition is for (if it's a single thing) or say "See Stmt" (if it's multiple things). Our federal return was accepted, and TurboTax did put "See Stmt" on our federal return.
My theory: In previous years, the adjustment comparable to this year's 8z was included as part of a total of multiple possible sources of income, so if the "Other" description was left blank it previously wouldn't be an automatic flag. This year, line 8z is separated by itself, so I wonder if a blank description of the income on line 8z is an automatic rejection by the system.
I'm tempted to print the return and write "See Stmt" myself and see if it's accepted. (It's not a form that I can find any way to access and override the entry--I can change it in the worksheets, but it doesn't change the info in the form that's filed.)
Don't know for sure if that's the issue, but it seems...plausible? What I do know is it's definitely frustrating.
