What is the payment address for Goldman Sachs

Call an Apple Card Specialist to see if they can give you one. See the following from How to make Apple Card payments - Apple Support

If your iPhone is missing or stolen, you can call an Apple Card specialist to make a payment.

You need to find your statement, the address is listed on the bottom of each page. But you will also need your account number. I just posted how to set up a bank Bill Pay app to pay Apple Card and the info to find these items is in this post.
