T4A(P) Tax Slip
 

I'm using Studiotax to report my taxes but when I try to make a NETfile it says I cannot proceed unless I enter in box 20 or 23 in the T4A (P) section. On my T4A (P) slip it only tells me how much I got but nothing else, boxes 20 and 23 are empty... do I just enter in 12 months?

Any help is appreciated!
