The max for CA SDI for 2018
The maximum SDI to withhold from employees' paychecks for 2018 is $1,149.67, up from $998.12 for 2017.

If the amount in box 19 exceeds this amount then Turbo tax will give an error message and fail to e-file. 

Box 19 must be adjusted to no more than the maximum limit. Limit may apply to all W2's having CA SDI entries.
