The question being asked is your S corporation required to file a Form 940/Form 941. Check the boxes for the forms listed that your S corporation files throughout the year. It is not asking for you to fill out and file any additional forms with your return. It is only asking what other tax forms you are required to file throughout the year.
You should have payroll and if you have payroll you are probably a Form 940/Form 941 filer.
