Presets not importing on new MacBook Pro 2020

Hello!

I have been using the same presets on Lightroom CC for over 2 years now on a Windows laptop. I just recently upgraded to a Macbook Pro and am not having luck importing my old presets. They have been downloaded from my purchase source to my computer. When I go to import them, I click on the download button and it just says "no preset or profile found here". I have been googling a lot but much of the info seems to be about different or older versions of Macs. Just curious if anyone could help me locate the presets on a brand new Mac. Thank you!
