Only adding a thought to this thread re efile 1065/1020s etc. 2 yrs ago I efiled one of my filings via TT, a year later I got a notice and a fine for NOT FILING!!! I got the acknowledgement via turbo tax which I suppose came from IRS... I then paper filed, registered, took pictures of me putting the forms in the envelope, putting the green registered mail sticker on, took pictures of the USPS recept.. I've had to mail those pictures to the IRS on a few occations.
I know of no perfect way to file due to IRS failures. Just paper file folks, take lots of pictures and save in your cloud storage for the TT files etc. :( :( :(
I do agree though that if you need to efile so you can get an IRS transcript you are stuck efiling!! :(
I always extend and file close to the extended due date. I was at a tax class; if you paper file its recomended to mail 2+ weeks prior to the due date to make sure you get your post marked by the due date and into the IRS mail received system to avoid the automated IRS notices of late / no filing. Best to all.
