TLS and SSL do not fit neatly into any single layer of the OSI model or the TCP/IP model. TLS runs "on top of some reliable transport protocol (e.g., TCP)," which would imply that it is above the transport layer. It serves encryption to higher layers, which is normally the function of the presentation layer.
