Get your taxes done using TurboTax

Why is there a 8915F-S that "can" be e-filed on 2/16 but a 8915F-T that "cannot" be e-filed?  The IRS site only lists a 8915F and that's all that is attached when I view a preview of my tax documents within Turbo Tax.  Really hoping this gets corrected so we can e-file.
