I got a 28% similarity score in my essay, mainly from references, is this bad?

I submitted my essay on turnitin, and got a 28% similarity score. The similarities came from the front cover that the uni provided us with, so that doesn't count, a few direct quotes counted too, but the rest was in the reference list. The whole reference list counted towards the similarity score, not one reference was spared. Is this a bad thing? Am I cooked?
