Krushna (Krishna) is not a Jain Tirthankara. In Jain literature he is generally treated as a historic king of Dvārakā who lived in the yuga called Dvapara, but Jainism does not elevate him to the level of a spiritual teacher or liberator in the way it does for the 24 Tirthankaras. The Jain path to liberation centers on the Tirthankaras and their teachings, not on Krishna. If you want, I can share more precise Jain sources on how Krishna is presented in specific Jain texts.
