Hello, I over contributed to my RRSP account with my financial institution. I have not claimed this money on any taxes yet. What do I do to avoid a fine? taxes are late

I over contributed to my registered account for my 2017 taxes by mistake by about $7300. I have not filed my taxes yet. I am well over the 90 rule.

Since I have technical not filed my taxes yet, can just use the $7300 in the RRSP account and claim the 7300 dollars next  tax year?
