In TurboTax, enter your actual December 31, 2016 balance of around $5,000. (Nothing from your 2015 Forms 5498 is relevant for preparing your 2016 tax return. Nothing in your Roth IRA is relevant.)
Entering the code R Form 2016 Form 1099-R has no effect on your 2016 tax return other than to remind you that the recharacterization was reportable on your 2015 tax return.
