If you e-filed your 2020 tax return there will be an Electronic Postmark Report which will have the date/time the tax return was transmitted and the date it was Accepted by the IRS, if Accepted. The Postmark Report will be included in the PDF of the 2020 tax return.
If you mailed the tax return TurboTax has no information on a mailed return.
