How do I check the status of my 1040 return or 1040X form?
The IRS has replaced the refund cycle chart with taxpayer instructions for using the IRS2Go phone app or "Where's My Refund" online at IRS.Gov.
Pub. 2043 states that Where's My Refund? provides an actual personalized refund date as soon as the IRS processes your tax return and approves your refund. Where's My Refund? is updated no more than once every 24 hours, usually over night.
Questions about the status of the refund or assistance with using the website should be directed to the IRS.
1040-X Amended Return:
The IRS has a tool for taxpayers to check the status of amended returns. Where's My Amended Return provides the status of a Form 1040-X filed for the current year and up to three prior years.
The taxpayer also can access it at IRS.Gov
