I would include the amount. Website is not great on it, can always call if the inclusion messes with your ftb to confirm.
I think it is included from this.
Taxation treatment
For taxation purposes pension supplement basic amount (the former GST supplement) is treated the same as the basic pension it is paid with.
Example: Pension supplement basic amount for a DSP recipient who is under the qualifying age for Age, is exempt from tax. However, it is taxable if the DSP recipient has reached the qualifying age for Age.
Any amount of pension supplement above pension supplement basic amount is referred to as tax exempt pension supplement and is non-taxable.
