Leviton DW15s-1BZ and DD0SR-DLZ on 3 way

Hey everyone. I’m new here and did some searching. I found some other posts similar to what I have but they weren’t exact. I have the two items listed above in the title and I am trying to wire them up. So far to avail. One box contains only a white (neutral), black, red, and copper ground. The second box (there is a picture below) has the same, plus a white and black wire taped together which you can see on the lower left side of the box. I can get more information as needed, but I figured I would start here. I have wired a few light switches in the past and quite a few ceiling fans. But I would say I’m still pretty new to this. Any ideas what might be wrong?
