How to submit Passport for stamping in USA

Hello Everyone,

I am currently located in USA and I am the secondary applicant in PR application. My wife is the primary applicant , who is in India. We received a passport submission request today. It is clear that my wife can submit it in India but I am clueless on how to submit my passport from USA. Can anyone guide me if I can send to NY VAC for stamping ? Mail received from IRCC addresses my wife.
Please guide me on the current prevailing process.

Thanks in advance !!
