Unfortunately this link goes to a coinbase 'general information' page which I already read. Coinbase does not appear to calculate gains and losses.
Other TT experts and TT Forum discussions referred to having coinbase generate a CSV file. FYI, the only coinbase CSV file it will generate is a "history file". That's good for getting transaction history, but then it is a "manual" process of sorting the transaction information to determine dates/cost basis, dates/taxable events and related proceeds.
Even after the laborious process of figuring cost basis, there is nothing I've found about where the einput is made in the TurboTax program.
