Did you know that Intuit's Accountants Community has an "Unexpected Behaviors" section? There is a reference to it in this thread, which might relate to your problem.  At least, the initial question relates to your problem.  Ignore the resulting tangent (definitely an unexpected behavior) discussion of charitable contributions.  Is it possible that the tax programs had a problem, they were fixed, and then reverted to the same error when something else was subsequently "fixed" ?
