If you don't feel that you are an employee, then you are in business for yourself and must file a Schedule C with your tax return. You will need to pay self-employment tax at 15.3 % in addition to income tax.
If you do feel that you were an employee, Form 8919 (it is in TT) is used to report wage income that was incorrectly reported on Form 1099 or not reported to you at all. It will require you to pay FICA and Medicare taxes on the payments (remember - you would have paid them anyway) but not the matching employer share. You will also have to prepare Form SS-8 (a request for determination on employee vs. contractor status). You will probably also upset your “employer”, because the IRS may contact him about whether or not he properly paid wages.
Form SS-8 is not in TT but is here http://www.irs.gov/pub/irs-pdf/fss8.pdf
