RRSP Contributions are not affecting my balance due. With/without the RRSP contributions do not change the amount due or refund? How can I fix this?

Are you Self-Employed? And have you had any "tax withheld" ?

You need to first make sure your RRSP Contributions are actually being posted on your tax return. Here are some common reasons why they may not be appearing on your return. Also if you are "Self-Employed", if you are making Self Employed CPP Contributions, the RRSP contribution will not affect the CPP contributions due.
