My guess is because IRS efile opens on January 29th....  can't transmit until then.

1041s are "business" returns. efiling for them is already open, but maybe not for ProSeries.

aahhhhh  .....    thank you

For what it's worth, I filed a 2022 1041 this morning that was accepted.

And I thought you just sat around all day drinking Fireball and pulling wings off of flies!🕷

I need a break from that kind of stuff every once in awhile 

I am having the same issue.  The return converts but will not transmit.  Please help!
