Keep asking around other bike shops. My old "dumb trainer" will not accept a standard skewer because of the typical cam lever -- which does not fit into the trainer's mounting axle. I have a "trainer skewer" that has a simple rounded end with the actuator cam simply a lever coming out the side of the skewer. Search the web for 'trainer skewer' and you'll see what it looks like. lots of them for sale on the web.
