Yes----and phones are swamped on deadline day. That happens when you wait too long. You can post questions here in the user forum and we may be able to help you faster.
For those who timely filed by midnight 10/17 and are REJECTED you have 5 days (up until 10/22/23) to correct the error and resubmit the return. No NEW filings will be allowed thru the TT system ... they will have to be mailed in.
END OF YEAR STEPS FOR ONLINE USERS
E-file servers are shut down for the year for personal returns. No exceptions! You won't be able to work on your return or get a copy of it after Oct 22.
If you have already filed your return I would double check that both federal and state were accepted here,

If you haven't filed or finished yet you only have until Oct 17 to finish and efile. If you efile by Oct 17 you should still save and print out the pdf file NOW so you can mail it in case your efile gets rejected and you are not able to get it to go through.
If you don't efile by Oct 17 you will have to print and mail it. If you don't finish your return you will have to switch to the Desktop program. So you might want to switch NOW. To switch from online to desktop and continue in the desktop version see this…….
