Got a CP05A notice. Letter says they want 3 pay stubs one being the end of year. Me and my wife both have 2 w2’s each. Should I send 3 stubs in general or 3 from each w2?

Main concern is if they want just 3 pay stubs ( including end of year ) or 3 pay stubs from each of the employers we had. Letter doesn’t specify 3 from each just says 3 pay stubs.
