I contributed 3500 to my RRSP however it is only showing 3300 on the summary page and I can t change it.

If the full amount of your RRSP is not showing up on your tax return, you should first check to see if your RRSP Contribution Limit is entered correctly and is more than $3,300

Some other reasons can be found in this TurboTax FAQ link: Why aren't my RRSP contributions appearing on my tax return?
