You have responses from two very experienced community members and one employee expert. I'm sorry you haven't found these responses helpful.
All of us, however, are trying to guess, based on the limited information you provide, what might be helpful to you.
https://www.irs.gov/businesses/small-businesses-self-employed/employer-id-numbers is a link to the IRS website explaining what EIN means.
Your tax ID is the same as your social security number if you have one. Otherwise your TID (taxpayer identification number) is one assigned to you that does not participate in the social security system.
If you are still frustrated, the best thing may be to find a friend or resource who can help you sort it out while physically looking at your documents. This is a public community forum and you should not post your personal information here.
Good luck and know that my wife is probably the closest thing I have to a supervisor and she wants me to stop typing and get over to the other house to watch the grandkids with her :-).
