Do not enter under Deductions & Credits anything regarding this rollover. It is not a new regular contribution to your IRA. Enter the distribution and rollover by entering the Form 1099-R under Wages & Income -> Retirement Plans and Social Security -> IRA, 401(k), Pension Plan Withdrawals (1099-R), then answer the follow-up questions.
The April 18, 2017 date has nothing to do with this since it is a rollover, not a new regular contribution.
