Amended returns typically take 8-12 weeks for the IRS to process, so you should wait at least 8 weeks before checking on the status of your tax refund. If it has been over 12 weeks since you filed your amendment and you have not received your refund, you should call the IRS at 1-800-829-1040 and speak to a customer service representative.
Also, the IRS isn't officially accepting your return until the due date. Don't worry, if you file early, you'll probably get your refund long before the due date. However, by law the IRS has until 45 days after the due date to get the refund to you before they would owe you credit interest on it. No matter when you actually send in your return, as long as it's by the due date, the computer will show April 17, 2017 as the official received date.
