Yes, that's a different Employer Supplementary Form -- INZ 1113 is for all employer-based Work Visas, and INZ 1235 is for SMC. You'll need your employer to complete the
INZ 1113 form, and return it to you so that you can submit it with your application.
Note that the "labour market test" part of that form (Section C) may be omitted by your employer if you wish to continue working in the role you currently hold, and you have been invited to apply or have applied under the Skilled Migrant Category based on this employment (again, due to the provisions of WK3.20.10).
