You can only transfer from 2023 at the beginning before you start 2024. So you would have to clear out 2024 and start over. Otherwise you have to enter any 2023 changes manually. Are you using the Desktop program or the Online version?
For Online....You can transfer it again but doing this will also clear out all your current entries. If you haven't filed, registered or paid you can try to clear and start over

For Desktop go up to File-New Tax Return to transfer from 2023 again.
