I have been trying to efile a return, but I get the duplicate SSN Efiling error.  I tried to resolve this through the fix duplicate return function in the e-filing center, but that simply states that the issue could not be resolved.  In the e-filing center, there is a separate file listing for the same SSN, but it only references one of the state income tax returns, and no client name is listed, just the SSN and return type.  When I click on that listing in the e-file center, I am asked to choose the file to open (since no file is associated with that listing).  I cannot delete this extra listing in the e-file center, the fix duplicate returns function does not work, and I and cannot e-file the original return.  How can I remove what appears to be the erroneous listing in the efile center that is blocking the ability to e-file the tax return?
