I'm in the same situation.  I have several 1040s with Form 5695 and am holding them just for this form.  As of Feb 5th, the form had a message that said This Form is Not EF Ready" and "Available for EF-filing on Feb 7, 2024".  As of yesterday afternoon, the message read and continues to read  "This Form is Not EF Ready," but then in smaller blue print a message reads "Update Available Now".  I have updated my system four times since last evening and still the form is not available.  Is everyone else having this issue now?
