Where do you upload the Coinbase CSV file?

I've already found https://ttlc.intuit.com/community/cryptocurrency/help/how-do-i-get-a-csv-file-from-coinbase/00/27533 and I have a CSV from Coinbase with my transactions (one buy and a handful of sells.) I'm ready to upload it into TurboTax online. Where are the exact instructions about where I go to upload this in TurboTax? 

 

The help articles seem to be missing this information and I've spent a few hours searching for a help article. I want to know the exact steps, not a list of information about what I need to get from Coinbase, or what is cryptocurrency.
