Us Customs Asking For Additional Information About My Identity To Release My Shipment - Time Sensitive & Minor

Hi all, not sure if my flare is correct but I need a little bit of guidance on what I should do.

To preface this, I'm a minor living in USA that runs (not owns) a clothing brand company under my brother's name.

I had ordered a shipment of products worth $888 from my manufacturer overseas to the United States. Last night, 1/22 the US customs picked it up for regular inspection, and today 1/23 they asked for additional information regarding my identity and the package recipient.

The required information include: - Social security number of package recipient - Proof of Tax - Legal name etc

I'm here asking about what I should do because I do not have any tax forms that are associated with my identity or social security number.

The shipping carrier is through DHL by the way.

Thank you
