I currently owe the IRS for a previous American Opportunity Credit, and now it says I am eligable again. What do I do?

TurboTax is offering me the American Opportunity Credit again, for my 2016 returns. The IRS says that I owe them for this credit that was awarded to me on my 2014 tax returns. Am I allowed to accept this credit now, even though I owe the whole amount for a previous year?
