How does winning state lottery affect my income tax?

I am an 18 year old student. My aunt bought a winning ticked for the florida Play-4 lottery, $800.00. She asked me to use my information to cash in the ticket. When I did, i received a W2-G form, and it said total income $800.00 with no taxes taken out of it. How will this affect when I file for my regular income... show more I am an 18 year old student.
