They gave possible reasons on the CP12 form. One was receiving advanced CTC which I did not. The other possibility was error on 8812 or not transferring 8812 amount to return properly. As I said the IRS guy I spoke to said all the forms looked correct and he could not understand the correction.
So you are saying reopen the original 1040 and try to make the irs corrections and get the number down that way. I was not even aware I could change anything in the TurboTax software after it was filed. It is not evident how to reopen it for editing but I will have a look. Thanks.
