efile problems with mentally ill client

What do you mean you re-filed?  Are you saying you amended or superseded the return?

In answer to your question, open the file and look for Form 9325.  That shows the e-file acceptance information.

Another thing you can look at is when on Homebase, single-click the client, then RIGHT click the client file to get the option to view the e-file history.  

I canot understand why you cant prove that the tax return was filed and accepted. You should have q copy of the retur and infact it is the aw that that you keep a copy for 3 years after the doo date. And with pro series you get a reply that the return was accepted and on what date it was accepted and there is your proof. If the tax return was not ever mark accepted    then action should have been taken a long time ago.I donot aim to offend [Removed]

way too much personal info on the client and not enough information on the tax filing. You should not have been able to e-file the return a second time. If it was filed and accepted you would have received a reject notice that the return was on file. If you did not receive that and the 2nd filing was accepted then the original return was not efiled or not accepted. The accept/reject is from the IRS system. Also the fact that they got notices saying not filed also leads to an issue with the original return. From the efile homebase you can get the efiling history. 

To me it sounds like you efiled and it was rejected and you didn't see it - or you thought you efiled it and you missed it. I've done that - looked at the efiles the next day and say HEY they were here yesterday and signed why didn't I efile? Now I count the efile forms and I make sure I am efiling the same number of files. Stuff happens. Say sorry, efile it and offer to pay the interest.
