No need to be concerned, this amount is being correctly entered on your tax return 🙂

When you receive a T4A slip and have entries in certain boxes, they post to Line 104 of the tax return - Other Employment Income. CRA considers certain benefits (Group Insurance Premiums -Box 119, Medical Premium Benefits - Box 118,etc) you receive when no longer working as employment income and they trigger the Canada Employment Amount deduction. 

A complete explanation of the T4A box number definitions and where they post on your tax return can be found here:
