I'm trying to get a WI return out that contains form OS which requires pdf attachments.  I have attached everything required, the attachments are listed on page 2 of the WI informaton sheet.  However there is a form W-RA being generated for mailing in the forms that are electronically attached.  And e-file instructions say that taxpayers  need to review and sign the W-RA before e-filing.  There are no signature lines on the W-RA.  Do I still have to mail in the other state return and requested attachments with W-RA even thought they are pdf attached to the electronically filed return and where the heck do the taxpayer's sign and date this form if I do have to mail it in?
