You should receive some type of tax document from either your company, or perhaps a third-party payer, that reflects this income. It may be that it just hasn't arrived in the mail yet. I wouldn't file until I had that document, as well as any other documents you're expecting.
Your Human Resources department should be able to advise you on what to expect.
