No, you are not supposed to enter the rollover as an IRA contribution. The rollovers do NOT count as contributions. The rollover is included in your total income, but it is not considered taxable income. Please look at your Form 1040; Line 4a should have the amount of your rollover and "rollover" should be written there. Line 4b should not have an amount of the rollover and, if that is your only 1099-R, it simply should be zero... If that is not the case, please go back, delete the 1099-R entry, and reenter the form again...please be sure to enter the form into the program exactly as it appears.
As to your deductions... standard deduction for 2018 doubled from last year; so it's entirely possible that it is a more beneficial deduction for you this year. Please read What's my standard deduction for 2018 for details.
