I have contributed some $ X for RRSP in 2019 and I have withdrawn the same $ X for my first time home buying in 2019 itself. In this case, can I still deduct that $ X from my total income while filing the income tax returns for 2019?
Yes, you can, but only if it was contributed 90 days prior to the HBP Withdrawal.
