I attempted to e-file a return Monday evening, and was prompted that software update must be done.  ProSeries was shut down, upgraded, rebooted, and return submitted.  I spent most of Tuesday travelling, and checked tonight for the acknowledgements from Monday evening and Tuesday morning. One return, the one I attempted immediately before upgrade, is apparently stuck at Intuit, no line indicating sent to IRS, cannot refile as check boxes say already at Intuit.  Updating acknowledgements doesn't help.
