I'll assume you haven't already filed the return. Is that correct?
If you haven't yet filed, here's how to correct it. I show 2 possible scenarios below.
You don't have to start over to correct a birth date. Had you finished your return (but not yet filed it) so the return interview is closed? If so, at the Tax Home page, look for a link Add a State. That doesn't really add one, but will open the return interview back up. When the interview is open, you can then navigate to correct your birth date.
Or is it this? Do you log in, and there's no evidence at all that you prepared a 2024 return in that account, and it's acting like it wants you to start one? If that's the case, you may be in the wrong account, and we can tell you how to look for multiple accounts.
