That's ok. You might need to add them together or just enter one if it's taxable. Look at your 2016 federal return. Did you take the Standard Deduction or Itemized Deductions? Do you have a schedule A?
Same for your 2017 federal return.
What 1040 form did you file? What deduction did you take on 1040 line 40? Or did you file 1040A or 1040EZ?
