QuickBooks Self-Employed (QBSE) doesn't have the ability to track multiple currencies. As a workaround, you can manually calculate the amount and convert it to dollars.
Here's how to manually create a transaction and add the calculated amount:
Go to the Transaction menu and select Add Transaction.
Enter the amount and a brief description.
Browse the Select a category menu and choose the best option to organize your transaction.
If you have a receipt, you can drag and drop it onto the form.
