cgt non resident calculator question

I am non UK resident, trying to work out UK CGT liability for selling an inherited UK residential property, using the calculator in https://www.gov.uk/guidance/capital-gains-tax-for-non-residents-calculating-taxable-gain-or-loss. There is a question "What was your total UK income in the tax year when you stopped owning the property? It says "Include your UK salary before tax, and anything else you pay UK income tax on. Do not include the money you made from selling the property." I do not have any UK salary. I do not pay UK income tax on anything else that comes from UK sources, as I have "NT" code and no tax is taken from my UK source income, and I declare everything and pay tax on UK sourced income (a UK company pension and some UK shares) in my residential country Australia. Should I answer 0 pounds, or put in my total UK income (approx 3070 pounds), as the question says total UK income, but below it says anything else you pay UK tax on (that I don't) ?

Hi,
You will declare it as zero as its not taxable here.
Thank you.
