Hi, the only available input box for business income is "Self employment Income reported on T4 slips (Box 81, 82, or 83)" . Do you mean that we have to enter box 21 on T5008 as "Self employment Income reported on T4 slips (Box 81, 82, or 83)" ? Because it's not reported on a T4 slip, it is on a T5008 slip.
