An amended Federal tax return, Form 1040X, can only be completed, printed, signed, dated and mailed by you. It cannot be e-filed. The IRS will take 16 weeks or longer to the process the amended tax return.
Do you need to make changes to the tax return that was already filed and where you have not yet received the tax refund or the taxes owed have not yet been paid since the IRS has not yet processed the tax return that has been filed.
Amended returns have to be printed and filed by mail. It can take the IRS up to 12 weeks or longer to process them. If you are due a larger refund than on your original return, your amended return should only show the difference and you will receive a separate check for it. If you owe money on your amended return, it will show only the new amount owed, you will have to mail a check with the return.
