Technically, you need to report all of your income, even
though that $10 probably won’t make a difference. You can report it as "Employment
income not reported on a T-slip" which is available in all versions of
TurboTax, including Free.
If you are intending for your Redbubble venture to be an
ongoing business, you can treat it as self-employment income. That way you can
also write off business expenses. In this case you may want to start with
TurboTax Standard. . You can always upgrade if you find you need more.
