Funds are always deposited to the Bank Account that is marked Default on your Checkbook profile. If you have only one Bank Account on file, it becomes your Default for sending and receiving automatically. To change the Bank Account you would like to deposit funds to, follow these steps:
Step 1: Go to "Settings" and then to the "Accounts" Tab
Step 2: Select "Add a new Account"
Step 3: Verify your new Bank Account
Step 4: Set your new bank account as Default
Once this is done - all future Checks will be automatically deposited to the new Bank Account you have just added and set as Default.
