Absolutely! I am having this issue too. Coinbase partners with a third party called CoinTracker who offers to tabulate one's gains/losses for a fee, of course! It's stunning that Coinbase is so greedy that it no longer calculates this information for its customers free of charge. It's also stunning that TurboTax still partners with Coinbase and makes it seem so easy to upload a .CSV file of your transaction history (not gain/loss because, again, Coinbase no longer offers this document), yet it does NOT work.
