I have some steps that you can use to track the test transactions, MAJ27.
You can create an expense for the amount that shows in the Spent column of the Banking page, and a bank deposit for the Received amount. Before doing so, please consult your accountant for advice.
To create an expense, here's how:
- Go to + New > Expense.
- In the Payee drop-down, you can create a vendor or leave it blank.
- Choose the bank that is connected to the online banking from the Payment Account drop-down menu.
- Select the Payment date.
- In the Category details section, choose the bank and enter the test deposit in the Amount field.
- Click Save and close.
Then, record a bank deposit for the same amount by following these steps:
- In the + New, select Bank deposit.
- Select the bank account from the Account drop-down menu.
- In the Add funds to this deposit section, select the same bank account from the Account column.
- Enter the amount and click Save and close.
Once done, go back to the Banking page and match the test transactions. I've got a sample screenshot below for reference:

Please let me know in the comments below if you have any additional questions about the process. I'll be around to help you some more. Take care and stay safe.
