If you printed and mailed the tax return then TurboTax will have no knowledge of when or even if the tax return were mailed.
Did you e-file your tax return and was it accepted?
You complete your tax return by finishing all 3 Steps in the File section. In Step 3, to e-file your tax return, you must click on the large Orange button labeled "Transmit my returns now".
After completing the File section and e-filing your tax return you will receive two emails from TurboTax. The first email when your tax return was transmitted and the second email when the tax return has either been accepted or rejected.
The emails confirm when the tax return was transmitted and when the IRS Accepted the return, if accepted.
You can also look at the Electronic Postmark Report which will have the date/time the tax return was transmitted and the date the IRS Accepted the return, if accepted. You will need to use Print Center and the option for all worksheets to have the Report included in the PDF.
