It depends on when you actually filed the return. If you had an extension (which gave you until 10/15/22 to file) but filed the return 6/15/22, then your amended return requesting a refund is due 6/15/25.
Per IRS topic no. 308: If you had an extension to file a return and you file it before the extended due date, the return is treated as filed on the date the IRS receives the return.
