Update this morning (Saturday, Feb. 11). The description of error message in TurboTax is the same, but the fix section is:
What needs to be done:
This return cannot be electronically filed due to a processing error on Form 8960, Net Investment Income Tax. This issue will be resolved on February 19, 2023. On or after this resolution date you may resubmit this return for electronic filing.
I'll be trying again on Feb. 19.
