The change was the total income amount on Schedule E.  The total was erased, which in turn changed the 1041 because the income no longer flowed from Schedule E.  Total Income is a calculated amount, so should not be overridden.  However, it would no longer autofill, so I had to override the blank with the correct amount.  I received an error message when I applied the override, but it has now disappeared.  The return had been through all reviews (so opened/closed many times) and the e-file authorization had been sent to the client.  The e-file authorization had the correct numbers on it. Tech Support does not have any idea as to why this happened.
