If you were told to not return for at least a year, any presence prior that period would be a trespass.
If you had not been told to stay off the property prior to that, what you received shouldn’t have been a citation as it requires prior notice that you are not allowed on the property before it is considered a trespass.
Im not sure when the police contact was made whether it was after you had been told to stay off the property or you were told at the time the police were called.
If the first, then I suspect it was a citation. If the latter I suspect it was a notice you are not allowed to return to the property.
to check on the ticket isssue; check Michigan’s court records and criminal records (available online) or call the police that responded to the call
