You have unfortunately encountered a known bug. The fix will be in the Feb 17 TT/Calif update. If you can override that field the correct method is 150DB. Overriding may prevent you from e-filing, though.
You can also fix it by editing that asset in the federal return and for the question, Elect out of Special Depreciation Allowance, check No. That will, however, change the computed depreciation deduction upwards on your federal return if the asset was placed in service in 2016, lowering your federal taxable income.
You can continue preparing other aspects of your return in the meantime.
