Why Turbotax is auto-populating unused RRSP contributions and 2017 RRSP/PRPP Deduction field with 1.00?

I did not contribute to RRSP this year. I have unused RRSP amount. Even though I did not populate any fields re: RRSP contributions, Turbotax has populated $1.00 in the UNUSED RRSP CONTRIBUTION and 2017 RRSP/PRPP Deduction fields. Why?
