2021 was the first year I had crypto transactions, and what a pain. Premier Desktop had no direct way to enter or import my crypto trades - and I had hundreds of transactions on 2 crypto exchanges! I ended up filing an extension to give myself more time...
After doing some research and consulting some other crypto investors, I ended up using Koinly for my crypto. I was able to get started for free, and then buy a subscription to download the tax forms I needed, in a format I could import into Premier Desktop. Koinly walks you through setting up read-only API interface to most Crypto Exchanges to import your transactions into Koinly. I did have to request a CSV file of transactions from one of my exchanges because the API doesn't let you go back very far.
It should be easier next year since Koinly keeps track year-to-year. It cost somewhere between $49 - $250 depending on the number of transactions.
