How Do I Trade In Device If S23 Ultra Is Purchased On Samsung.com Selecting AT&T?

I'm trying to understand if I have to trade in my Note 10+ to AT&T directly or if Samsung is going to want my device. I don't want to lose the $1,000 offer but also want to be able to get the free Galaxy Watch 5 correctly. In order to get the Galaxy Watch 5 you have to trade in your Note device but to who and what condition? I took screenshots below of what I see.

Edit: Now it keeps telling me "Your AT&T trade-in offer has been removed" after continuing on the website. I'm done, the site is trash.
