2019 Extended due date for extensions?

[Greynewfs]

I have 3 clients now asking for extensions for Form 1065.  Of course, ProSeries will not allow me to e-file it.  Any suggestions?

Isnt it an automatic extension, just like 1040s?

That's what I'm wondering.  Everything I have found is all about individuals.

But calendar year partnerships were due March 16th.  If the software won't let you file the extension I'm guessing they were December 31st year ends.
