If you have filed already, you'll need to amend. It is too soon to amend your return now. Once your return is fully processed, you can amend as soon as the federal amended tax return form 1040-X is available for filing in TurboTax. Use this tool to check availability of forms, including 1040X: Tax form availability. Currently, it is projected to be available 2/25/26.
