When is the Form 8615 going to be available? It was originally supposed to be available to file on February 5, then February 12, and now the site says February 20.

The forms are available if you are going to download from the IRS to complete it on your own.  However, e-filing is different.  Once the form is finalized by the IRS, it has to be coded into the special language the software uses and has to be thoroughly tested for calculations and e-filing acceptability.  IRS then has to approve it for e-file.  It always takes a little longer for a form to become available for e-file in a software program.  I hope this helps you understand the situation.  As of today, the Form 8615 is scheduled to be ready on 2/20/2020.  I truly understand your frustration and thank you for your patience.  See updates: IRS forms availability
