This is an annoying feature gap that they haven't solved for many years now. I've contacted support and this community on multiple occasions for this to be added, but TT is slacking on this.
I use CoinTracking.info too and it seems your best bet is to manually enter your trades or use the Desktop version which will allow you to import the .txf file. But we're in 2021, why in the world are they making us download a desktop/offline version to file taxes...
It's terrible, because using the Desktop version doesn't have all the great features of the online versions and if you want to have historical data of your tax returns reported nicely in TT online, you're out of luck.
TT please listen to your users and add this feature. Better yet work with CoinTracking.info, like you have been working with other crypto tax reporting sites and add better/seamless integration. You honestly should not even be offering a Desktop version to file taxes. Everything is online/web/mobile based these days. Please get with the times.
