To clarify, did you make a rollover, taking funds from an IRA and then returning it within 60 days? If yes, then you do not enter this in the IRA contribution interview under Deductions and Credits. You enter your 1099-R and indicate in the follow-up question that it was rolled over:
Or do you mean a recharacterization? Did you make a Roth IRA contribution and then recharacterized it as a traditional IRA? If yes, then please see How do I re-characterize a Roth IRA contribution as a traditional IRA contribution in TurboTax?
