Tax Free Lump Sum, do i deduct manually from total earnings?

I received a tax free lump sum at the end of my employment, it is a separate item on my payslip. Do I deduct that amount from my total earnings on tax return so that it is not taken into consideration for tax?

Hi chineseapology solley,
If it confirms it should be tax free, yes deduct this from the total.
Thank you.
