TCP and UDP are transport layer protocols; the OSI layer is layer 4 (transport)
because in the data link layer two routers communitate directly via a physical channel , whereas at the transport layer this physical channel is replaced by the entire subnet. In the data link layer ,it is not necessary for a router to specify which router it wants to talk to each outgoing line uniquely specifies a panicular router . In the transport layer explicit addressing of destinations is required.
Layer 3 i.e, network layer of the OSI model is used to IP addressing.
