You can withdraw the excess contributions (along with any earnings attributable to those contributions) to avoid the penalty tax, at least for the 2013 and 2014 tax years. You will have to pay the 10% early withdrawal penalty in addition to your standard marginal tax rate on the earnings, but that's likely much better than a 6% excess contribution penalty on the whole amount. Call your IRA provider and they should be able to help you process the withdrawal.
