I just went back to Amazon's site and what confused me is that they had Wonder Woman 1984 (3-D) pre-order listed and with it that Wonder Woman without a code Amazon link. Just browse down to the Wonder Woman 1984 (3-D)...
For those interested, I see Amazon has two different 4K releases of this movie. One is with a digital code and the other without a digital code is currently $6.00 cheaper on Amazon. I thought Amazon stopped that practice, but apparently not.
