Form 1116 Schedule B missing

I updated TurboTax today (3/11/2022) but still can't e-file because of this error message:

We can't e-file your return because we are unable to locate the attachment at /attachment/Form1116ScheduleB.pdf. Please go back and re-attach it. Then try e-filing again.

When I check the TurboTax forms list, this form is available and supported, and it appears in my return in the desktop Turbotax program.  I searched for the pdf but it is not on my computer.  Don't know how to attach it if I did find it. Not sure what to do at this point.
