Ok, this issue remains unresolved for PS23 1065/1120S extensions.  Can you please send it up the chain so that this issue gets fixed in the present time if only for PS24's sake?   

Even though you can uncheck the [__] EFile box and only check the [__] Extension box there were still some gremlins flaring up in this approach.  With the 1065/1120S returns with a Schedule F present [rolled over from PS22] I was still forced to go into 1065/1120S Schedule F and check the material participation box of Schedule F and fill in the Schedule F, line 30 lines that rolled over from PS22 before I could successfully file a 1065/1120S Extension. Yeah, I have no idea why either.

DO NOT LET THIS GO.  GET IT FIXED.
