Moved mining rewards to trading account

Hello Support,
I have an LLC that I mine a few tokens in and it is separate from my trading account for tax purposes. I need to create two different tax activity accounts. In the mining account I moved some mining rewards (300 HNT) into my coinbase trading account, but did not liquidate it. I do not want to import my coinbase wallet activity, so how do I make it so the 300 HNT is not showing a negative value?
