I called the GE office at IAH arrivals and they told me to come into the office to get it sorted. You can’t make an appointment for this kind of thing so I had to sit and wait.

fortunately it was quiet and the officer came out within 10 mins and asked if I had an appointment. I said I needed to add my Green Card and he took the card and my passport away, having written down my pass ID number. 2 mins later he returned and it was done.

When I got home I could see the Green Card in my profile on the TTP website.
