Since I don't think anyone is actually reading this, I am posting the directions for how to access your purchased Cricut images that you've already linked to your account, in the new (2020 v5.7.24) version of Cricut Design Space, so that I can find it again, instead of spending a couple hours in Frustration-ville. I looked everywhere online, after spending a ton of time trying to find it on my own - all to no avail. So, Eureka! - I just found it, and here it is, in case anyone else is looking for their purchased cartridges. (Cricut keeps improving Design Space, but every time they do, something disappears down a rabbit hole.)
So first, in Design Space Desktop, click on 'New Project', then click on 'Images'.
In the left column, at the top, under "Highlighted categories", choose "Image Sets", then on the left, click on "Ownership", then "Purchased". Magically, your cartridges will appear!!!
