Tax form availability is subject to change. It is not at all unusual for the 1040X to not be available until late February, so you will have to wait.
It is too soon to amend a 2024 tax return. You have to wait until it has been fully processed by the IRS. Sometimes the IRS catches and corrects mistakes you made. And the Form 1040X you will need is not available yet. Amending too soon can cause confusion and long delays.
