Entering unused RRSP contributions from line B of your 2023 RRSP Deduction... produces odd results. If I enter an amount, the refund is $10,000 higher than if I enter $0

Can you possibly take a picture or screenshot of where you are at when you enter the unused amount which makes your refund go so high?

The first photo shows the refund with no Unused RRSP entered and the second photo shows the refund amount with the Unused amount entered and the screen accepted so that the refund amount is recalculated. 

It looks like it is trying to take a deduction of the full $70,000. If you enter an amount to carry forward, does it lower the refund?

Yes, the amount entered directly impacts the Tax Refund, so, if $1,000 is entered in the Unused RRSP/PRPP contribution amount the refund is less than if a greater amount is entered.
