What are all past tense helping verbs?

The list of helping verbs I remember from 7th grade are:

is, am, are, was, were, be, being, been, has, have, had, do, does, did, shall, will, should, would, may, might, must, can, could. The ones that are past tense are:

was (ex: "He was gone to the parade.")

were (ex: "They were gone to the parade.")

been (ex: "They had been gone to the parade.")

has (ex: "She has gone to the parade.")

have (ex: "They have gone to the parade.")

had (ex: "She had gone to the parade.")

did (ex: "They did go to the parade.")

should (ex: "They should go to the parade.")
