Where do I fill in the amount received for travel allowance?

I am struggling to find the tab where I need to fill in the amount received for travel allowance, where do I fill in the amount received for the travel allowance?

In the opening questions to your Tax Return, you need to answer "yes" to the question:

"Do you want to claim expenditure against a travel allowance?"

Then the section with Travel Allowance details will be automatically generated further down in your Tax Return after the Medical Section.
