How can I retrieve the remaining unsold cryptos that I have after a certain tax year

My taxes with crypto have became super complicated as a US resident. As a result, CoinTracker is not able to support my needs. So, I am trying to consult with a tax accountant to handle my transactions for this year. I know that CoinTracker reads my transactions that I made from the previous years, knows at what time and price I bought cryptos, and computes the best cost basis schedule for the sales I’ve made. My tax accountant needs to know the remaining unsold cryptos after calculating the cost basis. Namely, he would need to have a list of remaining unspent cryptos, the price it was bought, the time it was bought and the remaining amounts of it (after considering the cost basis schedule).

How can I retrieve this information?
