refund status

Turbo Tax says return was e-filed on 4/28/21; however I did not receive a notice of such from IRS as I did in the past. Turbo Tax asks me if I want to "Continue" when I open the program! Strange since return was filed! Many calls to IRS, but the message is that they are reviewing the return. It's been two months. Senior couple, no kids, nothing unusual except receipt of Unemployment Compensation during COVID shutdown of my workplace. What is the holdup on my refund? Any ideas? Any suggestions on how to get a person to give an answer at IRS?
