Turbo Tax says I cannot e-file my 2022 1040X because I didn't e-file my 1040 using TurboTax

Trying to e-file my amended 2022 return.  I e-filed my 1040 and can view my e-file status.  Both federal and state returns show as accepted.  However, when I attempt to e-file the amended (1040x) return, TT shows the message:

"Unable to e-file. 
It looks like you've prepared a federal amended return form 1040X. 
It also looks like you haven't e-filed the 1040 through TurboTax.
..."
Is this a bug, or is the feature not yet ready?
