The IRS will attempt to deliver payments using the information that they have on file. If that does not automatically forward to you, you will be given a chance to update the information at a later date. There is not yet a way to update information that has changed, or in otherwise incorrect or out-of-date, but it is expected to be available soon through a portal that the IRS is developing.
