IRA Contributions do not come out of your paychecks. That was probably to a 401K Plan. That comes out of your pay pretax and has already been deducted from the wages in box 1 and you can't deduct them again. Do not enter them under Deductions & Credits.
IRA Contributions are made outside of work with your own money and should be entered under Deductions. They may or may not be deductible.
