OK,
I also called Turbo Tax Call Center. They had no record of issues for printing with 2d-barcodes, and thus no ETA for a fix.
Additionally, I tried reloading everything on a totally new Machine (but same files... I'm not going to mess with reentry) so that eliminates caches, etc. But that also didn't work.
Finally, I resolved to simply Print, and put a note in it. Apparently, MO has different addresses for 2d-barcodes, so it likely goes faster if you have it, but it doesn't seem to be required to file. https://dor.mo.gov/contact/individual-income-tax-information.html
FYI, my version is Windows 10 Desktop App, Full Business, etc.
