You said above that your first return has already been filed and processed and that you have even received your refund. So now to add another W-2 or to make any sort of correction/addition to your 2021 tax return you have to prepare and file a Form 1040X----that is an amended return.
Going forward--next year wait for all of your tax documents and do not file your 2022 tax return until you have all of them to put on the same tax form.
