Hi
I see you are trying to implement a Low Pass filter with a cutoff frequency of 20Hz so the above documentation would help you with what to put in numerator and denominator while implementing.
Kindly refer to this documentation on how to implement filters using Transfer functions.
https://www.mathworks.com/help/simulink/slref/transferfcn.html
Hope that resolves your query

Hi,
I understand you want to use transfer function to write a filter but you are stuck in the mathematical formulation of this. Could you provide the model details/implementation?
You can have a look at these and see if it helps.
