If your address was incorrect on your Federal income tax return, and your refund was returned to the IRS, you must contact them to notify of the change. You may refer to the IRS website's Topic No. 157 Change Your Address - How to Notify the IRS for instructions on the appropriate forms to complete and send.
If you were expecting a state refund, you must contact your state's Department of Revenue as well. For more information, you may review the FAQ: How do I contact my state Department of Revenue? https://ttlc.intuit.com/replies/3302452
