CA 540NR Error

I'm trying to help my in-laws file their CA tax returns and I keep getting a message about Line 12-State Wages does not equal the sum of the CA wages entered on the Form W-2 worksheet.  They are both retired and do not have a W-2.  I looked at both the Federal and State worksheets I completed in TurboTax and I checked all the boxes stating they do not have a W-2.  This might be one of the issues - they moved to Nevada in 2020 and have not contacted OPM regarding no longer being a CA resident so they still have CA taxes taken out of their annuity.  I have entered 0 in box 12 of the 540NR form but it will not accept that amount.  I would appreciate any suggestions on how to rectify this issue.
