Here is the page that tells you what you need to do. Check and see if the form (look at the number) your employer has already done is the same one needed for this visa. It is
very likely that you have already given most of the evidence needed, in which case give a cover letter making the connection to your residence application which is already being dealt with. And by all means, tell them that your employer has already done the questionnaire, so please can they refer to that, telling them why!
