This worked for me, my daughter mistakenly filed her taxes and did not mark that she can be claimed as a dependent on another's taxes (12a). When I tried efile, of course it failed with this error code.
We had my daughter amend her return and e-file. I got an IP PIN for myself, tried to get one for my daughter, but she's not 18 so we couldn't. Just to be sure, we got an IP PIN for my wife. Entered them into TurboTax and refiled using efile and I got a confirmation now that the federal return was accepted. WHEW !!!
Now waiting for State to be accepted, they take just a little longer. Finger's crossed.
