RRSP withdrawals

Hey there, I withdrew money from an RRSP it is a group benefits plan where I can withdraw anytime, I am 26, I did not withdraw it in accordance with any home buyers plan or life long learning plan. I attempted to report it as income on my taxes. I placed it in like 12900. The income however was not included in my taxable income. It was included as my total income but not taxable why is this?
