Hello @frank4bugs ,
There are two different ways you can do this.
1. Go to Banking-->Make Deposits. Choose the correct bank account the deposit is going to. In the 'Received from' column you can create an 'Other Name' type of name, for example 'RBC' or 'Scotiabank'. In the 'From Account' column, enter the income account you want to post this transaction too. I would suggest using QB Desktop's 'Other Income' account, as it is not sales income resulting from your operations. Enter the amount, and Save & Close. This will now be shown as a deposit in your bank account which you can check off on the deposit side of your bank reconciliation.
2. You can also enter this at the time of reconciliation. Right click on the bank account in the COA, and choose 'Reconcile'. In the 'Begin Reconciliation' window, enter the ending balance as you usually would. Tab down to 'Service Charge' and enter service charges date, and your account for Bank Charges. Tab to next field that says 'Interest Earned'. Enter amount of cash bonus from bank, date it was received, and change the account (which is defaulted to 'Interest Income') to the 'Other Income' account. Continue with your reconciliation as you normally would.
Either of these will get the result you are looking for.
Good luck!
