Your DNA propagated on to any profile that shares a direct ancestor with you (so not just your own ancestors, but also your cousins). It does this through every such connection in Wikitree, out to 7 steps away from your profile.
The only way to have your DNA test stop showing on Lewis’s profile (other than the drastic step of removing your DNA info from Wikitree entirely) is to disconnect Massey from Lewis.
You commented on Massey’s profile months ago, and someone commented on Lewis’s profile in 2015, saying she should be disconnected. There has never been objection. So I’d say just go ahead and disconnect them.
But: I would place a research note on Lewis’s page with a prominent heading about his disputed children.
Then, Massey’s profile needs work anyway, but part of that work should be a clear narrative explaining why it is very unlikely she is the daughter of Lewis. If your DNA has no matches to descendants of Lewis on websites where you compare, that can be part of the evidence.
