The connectivity issue with the IRS Modernized e-file system has been resolved. We are now transmitting e-filed returns and receiving acknowledgements normally. You may experience delays in receiving acknowledgments from the IRS while we address the backlog. Thank you for your patience while we worked with the IRS to resolve this issue.

Update
We are continuing to work with the IRS to investigate connectivity issues with the IRS Modernized e-file system following IRS maintenance to its e-file system on Sunday, which may delay IRS e-file transmissions and acknowledgements.
You can continue submitting e-files and electronically filed returns that are due are considered timely filed if submitted by 11:59 P.M. local time on the day of the deadline. Taxing agencies use the date and time of when the e-file was transmitted to Thomson Reuters and we received it, as the timestamp to determine if it was timely filed.
We’re working with the IRS to resolve the issue and will provide updates as more information becomes available.
