I was lucky enough to get a good Lacerte analyst. Even though the original "e-file Activity Report" showed a transmission failure, she made me look at the dropdown list item "Condensed Activity" (as opposed to "Complete Activity") which showed the return was actually accepted by the IRS & state. However, the usual Acknowledgment Letter was nowhere to be found at the time. Then, today it materialized. Will wonders never cease? Bottom line - I'll make sure to install updates before any and all e-filing. Good luck!
