I had the same problem in Premier Desktop. I used CoinTracker (there's a link to it in Coinbase) to consolidate my Coinbase and Coinbase Pro accounts and then in the tax area it had a button to generate a downloadable .txf file for TurboTax Desktop/Download versions. Once I downloaded that file I went back into my return on TurboTax and in the menu bar clicked File>Import>.txf files and then selected it from the downloads folder (or wherever you put it.) and it went right in. I did have to rename it in the summary screen.
I think this would work for other exchanges if you can either bring them into CoinTracker or if they can generate a file in .txf format. Good Luck.
