That's someone's name? And you want to know how to 'find' his 1040, online or from the IRS? You can't. He can file forms to request an old copy, if that's what you mean? Do you mean he needs to file one now, and doesn't have one, because this is the first year that the IRS isn't sending them out? You get them online at IRS.gov, or pick one up at a Post Office or accountant.
