Starting a New Tax Return in TurboTax Home Business 2020-Mac

[cami2]

I have completed two different returns in TurboTax Home Business on a Mac.  When I open the program, it automatically opens one of the recent returns that I've filed.  I can't figure out how to start a completely new return.  Can you help?  

Thanks.

In the top menubar, can you click on File>New Tax Return?

I don't use a Mac, so if you can't do that, I'll ask someone who does to help you.
