Hello, i-p-lemus.
I'm here to provide more insights about the unrealised gain or loss in QuickBooks Online. The unrealised gain and loss account is an expense account and will be shown only on the P&L report and not on the General ledger or Trial balance. What's on the Trial balance is asset, liability, and equity.
You can also pull up reports like the Transaction Detail or customize the Customer Balance Detail and Vendor Balance Detail to view unrealized gains or losses.
To learn more about Home currency adjustments when using the Multi-currency feature in QuickBooks Online, you can refer to this article: Home Currency Adjustments. It also contains sections of frequently asked questions and can guide you where you can see your Home currency adjustments history.
