Hi:
I had this problem filing the 2024 return (and also noted it in this thread when filing the 2023 return last year). I can see the signed form in the Tools/Attachments menu, but see the UNsigned form in the Print screens. While this is not very comforting, I hope it is being transmitted properly. It's probably a good idea to keep a copy of your signed 8453 form for your records.
Good luck!
