Losses available to be carried forward

Hi there, Hope you are doing well. I've just file the tax return and found that I missed to state the amount in box 47 mentioning the losses available to be carried forward. Would it be possible to advise if it is necessary to input this field? If this is the case, should I add up the amount of the available losses of this year together with previous years in box 47? Thanks for your help! Kind Regards, Mike

Hi Mike Tong,
If you hav not used any this year and the figure is already showing on your previous return you are ok.
Thank you.
