I put $6000 into a Roth IRA. Then, I recharacterized it into a non-deductible Traditional IRA, when it was worth $6102. How do I report the $102 that needs to be taxed?

I assume that the $102 is earnings that should be taxed as income, but I don't see it listed on any worksheet. How do I tell TurboTax that I earned it during the recharacterization?
