Uncovered this issue today. A california S corp return in which Pass thru entity tax is selected was unable to efile the Federal extension. (not even the California extension, just the Federal extension). When I unchecked the box for PTE return, then my Federal extension was able to be efiled. Before this, the program gave me an error message that said " Unable to copy record from PTDATAS24.db. The given key was not present in the dictionary".
