How do I print my 4868 extension form after e-filing it through TurboTax Easy Extension?
Simply sign in at TurboTax.com with the same login you used to e-file. You'll see a link where you can print the 4868, right underneath your extension status.
The IRS does not have a receipt of your extension request filing. You can get a free transcript for your Record of Account which will show the date the extension was received by the IRS. You have to complete, mail or fax a Form 4506-T to get this transcript type - http://www.irs.gov/pub/irs-pdf/f4506t.pdf
Or you can go to the following TurboTax website for the status of the e-filed extension at no charge. If the extension was received and accepted, there will be date/time stamps for when it was received and for when it was accepted. Click on the Print this page icon in the upper right corner of the screen - https://shop.turbotax.intuit.com/efile/efile_status_lookup.jsp
