Heres the release dates so you can see when the programs themselves are finalized...there have been forms in other years that had a yellow bar that shouldnt have been there and you could click the X in the corner of the bar and still file it, but its still pretty early for that for 2019 forms.  Business Efiling opening so early I thought was more for people that need to file business returns that have fiscal years and use the 2018 forms
