Look carefully at your input for the wages, especially in the Section for Electronically Filing (W-2 State/Local) In that grid, you generally should only have entries in the 1st two columns. Notice [O] for the other columns as overrides.
Another possibly is box 12 entries that create something that is federal deductible and not OK deductible. I know CA adjusts for code W (HSA). I don't know OK, so maybe look for the amount of the adjustment.
