After you file

Was this income reported on a 1099-misc with the amount in box 7 ?   

Is the IRS saying it should be self employment and you need to pay the SE taxes on it ?  

If you said the amount was supposed to be wages but the employer put it incorrectly on the 1099 then is there a form 8919 ?   <a rel="nofollow" target="_blank" href="https://www.irs.gov/forms-pubs/form-8919-uncollected-social-security-and-medicare-tax-on-wages">http...>
