If you have participated in the HBP and carried your information over from the prior year (or imported your tax slips from CRA), it's quite common to see an amount on Line 129 - RRSP Income. However, $6.00 seems awfully low for a repayment amount to the HBP.
I'm going to suggest you contact our Support Team and see if they can determine where this mystery number is coming from.
