My R-1 one has an RD Box and I'm told to "Enter boxes RD, RM, RP and RR in the appropriate self-employment statement.
However, if you enter the amount in the self employment assessment section, the federal return double counts the amount because it is already pulling the amount from your T4A.
If you don't enter the amount in the self employment assessment section, the federal return is correct (it pulls the T4-A) but the provincial return does not show the income.
