The IRS is behind on millions of returns. Nobody from TurboTax has any information on a mailed in return. The person who answers the phone at the IRS might have an answer, but most likely your return is in a pile of mail somewhere waiting for a person to open it.
Some people who work at the IRS believe that they will not be caught up with their 2020 returns this year. If you have a refund, they will pay you interest on the money when they process your return.
