Missing Crypto Transaction - High Capital Gains

I did my crypto taxes using multiple tax calculators and all of them are showing extremely high capital gains. I used a fix amount to trade with and at the end of the year I was roughly 80% in the red. I used Kucoin as a crypto exchange and when importing my account to the calculators, I had a lot of missing cost biases and my end of year balance is completely incorrect. I audited some of coins that the calculator said I had a balance of and I was able to find a few of the missing transactions and add them but there is still quite few missing. I am not sure what to do about this. Any help would be appreciated.

The IRS released a spreadsheet of what they expect to see used for tax returns. If you create the spreadsheet, you will have everything you need. Here is a picture of the spread sheet they used as an example at the IRS Tax Forum 2021.
