TurboTax Business - State Return Won't Launch

[john-ct]

Further to previous reply:

This year, for a NY Business return, I had to wait until the day after the one shown in the table for it too work, so don't take it as gospel.  Doing your taxes promptly has downsides.

Unlike your experience, a phone rep emailed me the NY Businees Tax (only) chart after he figured out what the problem was. 

I found the source page by trial & error today so that I could answer your question.

Good luck.
