Make sure that your IRA custodian knows (and will report to the IRS) that this is a Rollover Contribution, not a regular contribution of new retirement money subject to annual limits. Generally this is done by properly filling out the IRA custodian's paperwork to indicate that this is money being rolled over from another retirement account.
When reporting such a rollover in TurboTax, do not enter this as a new, regular IRA contribution under Deductions & Credits -> Retirement and Investments -> Traditional and Roth IRA Contributions. Enter the Form 1099-R exactly as received under Wages & Income (or Personal Income) -> Retirement Plans and Social Security -> IRA, 401(k), Pension Plan Withdrawals (1099-R), then answer the follow-up questions to indicate that you moved the money to another retirement account and that you rolled the money over to a traditional IRA.
