No one can check anything for you in this user forum. View/print your return and see what address is shown on it.
If you can't figure out what the problem is, you'll need to phone the IRS for assistance anyway and to have it redelivered to the correct address. Are you in the USA now or in another country?
If you are in the USA, we can tell you how to speak to a live agent at the IRS.
If you are outside the USA, we can tell you how to call the IRS International Taxpayer Service Call Center.
