Thank you for your response. I tried to follow your instructions, but when I am in the Forms section of TurboTax Business, there is no "Postmark Report". I looked very carefully, because I do not want to waste your time. Please advise.
P.S. "Tax Act" is a misleading name! Thank you for bringing it to my attention that it's a filing company. I thought it was an IRS database, because I found it on a google search for checking e-file records with the IRS. However, the physical letter I received stating I owe a penalty for not filing is definitely from the IRS.
