Amendment Error: Your transmission didn't go through We could not e-file your return for the following reason: Tax Year 2023 transmissions are not available.

I received an adjusted form after transmitting taxes.  Upon trying to retransmit, I'm receiving this error:
Your transmission didn't go through
We could not e-file your return for the following reason:
Tax Year 2023 transmissions are not available.

Additional context:  Both state and federal were accepted over a month ago, and federal refund has been paid, but not state.
