So, I'll follow-up with what happened.. I did end up getting in touch with a representative who went over the file. First off -- all of the "Wheres my 1040X?" status messages -- were related to the automated adjustment for the UC. The representative did have additional information related to the actual 1040X that was submitted. It was assigned to an IRS employee on July 23rd, and he expected that it would be completed within 4 weeks or so -- with a mailed check to follow. So, in short -- continue to wait and do not file an additional 1040X -- even though it now says the 1040X was completed.
And to answer my own question -- the updated 1040 in TurboTax should reflect the actual filed return once everyone does their part and the adjustments are made.
