The client letter is wrong.  It needs to be filed on paper.  Will tag an Intuit moderator to look into fixing that.

IT-4708 may be e-filed from 2018 but Intuit has not been approved for any of their tax products.  See this file published by OH DoR: https://www.tax.ohio.gov/Portals/0/pass-through_entities/File%20Uploads/MeF%20Approved%20Vendors%20L...

According to Intuit ProSeries, the form is not approved for e-filing either: https://accountants.intuit.com/_intuit/accountants/tax/2018/proseries/fragments/resources-release-da...
