How can you dispute when you parents have claimed you on their taxes and screwed you out of your refund even though you supported yourself financially?

If you're sure you're right, print your tax return (claiming yourself) and mail it in.  Don't e-file it.  When the IRS receives two tax returns each claiming the same social security number, they will contact both taxpayers and ask for supporting information.  Then they will determine who has the right to the claim according to IRS rules.  Winner gets the exemption; loser gets billed for the additional tax, plus penalties if any.  This all may take a while of course.
