Turbotax only has box 016, and 018 in their form, but I do not have these on the form I received from Service Canada.
You don't have to enter those boxes as seen in the Canada Revenue Agency (CRA) link: T4A slip: Statement of Pension, Retirement, Annuity, and Other Income. The number is information only, not to be included in your tax return.
Please see the image below for directions on where to find and enter box 20 of your T4A.
Thank you for choosing TurboTax.
