Line 12900 is for Registered retirement savings plan (RRSP) income from an T4RSP, Statement of RRSP Income slip. RRIF income doesn't go there, it goes into different spots depending on what kind of slip you got.
Thanx for this. As I said, my income is correct so I assume that the income from RRIF is included at the line for pension income. Is it something I need to worry about?
