I cannot say for sure, but that's what New York Taxation and Finance employee told me, although she wasn't 100% sure either.  She did say she didn't think any software program would have the time to develop an electronic form in time for the tax season.

It would be nice if ProSeries at least informed us as to what was going on with this because the employee I spoke with on their help line did not know at all either.

Regardless of what happens, you will still need to file a Form CT-3-S for the entity as well for purposes of the fixed dollar minimum tax.  It's safe to say that the CT-3-S will NOT have anything related to the Pass Through Entity Tax, as that form was already finalized on the New York Taxation & Finance website.
