IRS states they have not received my tax return, and Turbo Tax portal is showing the status as received

Hello, I logged into my account on IRS.gov, and it states that they have not received my 2020 tax return; however, I filed by May 15th, and in the Turbo Tax portal, it shows that the IRS received my return on May 21st and to expect my refund by June 11th. I was not necessarily expecting the things to wrap up on time, but I am concerned that the IRS is flagging my account as not having received a tax return for 2020. I do not want to accumulate any penalties of added fees for late filing, so I was wondering if this is something that is commonly popping up due to backlogs, or should I be concerned about an error somewhere in the process?

Thank you

Jennifer
