So, we had a client that this happened to last year and she is STILL dealing with it.  Social security had her SSN as deceased.  She had to paper file multiple times in response to IRS notices.  She went to SS and they removed the lock on their end, but IRS said SS still had it locked.  She still hasn't gotten her refund as of a week ago.  She contacted her congressman who said this has happened to thousands of people and told her to get an extension until they can try to get this resolved.  I'm so sorry for your client.
