They are definitely asking about payments you make to a pension and not payments that you receive?
If the former, then it's a first and I don't understand why it is being asked. As you are only receiving ESA(CB) there are no potential checks on what you are spending your money on and your ESA(CB) is fixed and cannot be increased by your actions.
May it's worth your getting face to face advise, do an internet search for "welfare advice" with your postcode, town or county.
