This seems to be an ongoing issue with Ohio each year.  It is extremely inconvenient and only seems to get resolved when enough people complain.  Your list of available forms is indeed useless since there are NO DATES other than 15 days after final release but hmmm no date for final release so no help there.  All forms should be available when filing season starts...period!  Get your team (software engineers aren't known for their proactive approach) going so that we can actually start the season on time....you sure want your invoice paid timely but your product isn't timely at all!
