Hi there TurtleHermit,
It's important that all your transactions be entered correctly for your books to be well balanced. QuickBooks Online is a great tool able to connect to your bank so that you can match them to the transactions in your books. I can provide some information about matching.
QuickBooks Online can match one transaction in the banking tab to more than one in your books, so what can be done is you create the transfer from the chequing account to the USD account by going to the +Newbutton, then Transfer. Enter the amount in CAD for the chequing account, then manually adjust the exchange rate in the text box so that the value in foreign currency is total to the amount that was deposited in the second account.
The second step would be to create the expense for the fees, by going to +New, then expense. Enter the information for this expense, then for the payment account, you'd need to select the bank account from which the money was transferred, which in this case would be the CAD account. Once done, hit Save.
You can then go match these two transactions by going to the Banking tab, then click on the transaction's description. Select find match, then put a checkmark beside both the transfer and the expense to match them to the bank transaction.
If you have any other questions, feel free to reach out here.
