If you made a slight typo it won't have an effect on the deposit of your refund (if your return was accepted). You could always call the IRS at 1800-829-1040 to notify them or complete IRS Form 8822 (Change of Address Form). This would be necessary since when you file, your new address in the IRS system will be with the wrong address.
Below is a link to the instructions and the form.
