After you have e-filed your Application for Extension Form 4868 and you want to print your filed extension, log in to your account and access your tax return. Next, proceed to "Summary/Print" (navigation bar) on left side of screen followed by "Print Return".

If you file the Form 4868 electronically, be sure to have a copy of your prior year's return; you'll be asked to provide your prior year's adjusted gross income (AGI) amount for verification purposes. Once you file, you'll receive an electronic acknowledgement that the IRS has accepted your filing.

No confirmation will be provided if you use a paper Form 4868 to request an extension and send it through the U.S. mail or an authorized private delivery service. If that's the case, you'll have to contact the Internal Revenue Service (IRS) to ask about the status of your extension.

The most convenient way to check on a tax refund is by using the Where's My Refund? tool on IRS.gov. Taxpayers can start checking their refund status within 24 hours after the IRS acknowledges receipt of the taxpayer's e-filed return.
