EF Status has been "Received by Intuit" for over a day now for an 1120S extension which was efiled. Usually they are approved by the IRS in less than an hour. Is there a reason for the delay, and will Intuit get the extension to the IRS by the deadline tonight?
Have you tried highlighting the returns in the EF homebase and then clicked on the e-file button and selected update acknowledgements?
Sorry, that's all I have for ideas. About all you can do is wait for them to clear or try another call to support.
You should be good with the postmark date at Intuit being timely, but a paper extension does provide a safety net to allow a better night's sleep tonight.
