I had the same issue using Desktop software. I learned that the section you're looking for is available only in the Online platform. So you'll need to use TurboTax Premier Online program to complete your taxes, OR enter each individual crypto transaction manually. I didn't have that many transactions, so that's what I did.
I have seen several users, though, complaining that each transaction uploaded from a CSV file had to be verified. So you still will possibly have to review each transaction on an individual basis. See the TurboTax FAQs that I'm sharing below for additional info.
How do I import my cryptocurrency transactions into TurboTax?
How do I upload a CSV file of my crypto transactions?
