It is indeed a lame reason. According to Intuit, this is because they have not settled one of the forms. I'd have to go back to find out which one but I think it was something like 113. I did not have the problem and I have no corporate income whereas my wife has the problem and has corporate income.
The advice from Intuit was just to keep trying.
Perhaps Intuit will have the common decency to advise us when the problem is resolved.
