Using the TurboTax tax preparation software there will not be a DCN because you did not use an ERO, your tax return was self-prepared.
There will be included an Electronic Postmark Report which has the date/time the tax return was transmitted and the date the tax return was Accepted by the IRS, if accepted.
Click on Forms. When in Forms mode Postmark Report will be listed at the bottom of the federal tax return forms, schedules and worksheets.
