I can't make the background transparent with the quick selection tool

Hello! I recently just got the Photoshop Elements 2020. I used to use photoshop back in 2017, but I see things have changed. I mainly use photoshop for its quick use of making a photo's background transparent because I like to edit photos. But since I've gotten the 2020 version, I can't make the background transparent? It just turns to white. I'd appreciate the help!
