I think this came up some time ago on the manual retract for TT slides. Look on the back of the electric motor for the slide. There may be a tag that shows using a 1/4" hex bit inserted into the hole behind the tag and using an electric drill. On our non-HL TT that we had, there was a manual crank hole under the steps, on the opposite from the slide. Had to use the stabilizer jack handle to do it.
