Where do I enter T4A(P) info

[SAGB]

You can not enter Box 20 of the form because Box 20 is the total of several other boxes.  You must fill in the boxes that create that total.  Those boxes are Boxes 14,15,16,17,18,19.  When you fill out those boxes, Box 20 will populate itself.  To do that, click Box 20, and the input fields for 14,15,16,17,18,19 will present themselves.  Fill them out according to your T4A(P) slip you received from the government.  When you select "Save & Close" it will do the calculation to fill out Box 20

How do I enter Box 13? (Onset or effective date) or is it not necessary?

[TurboTaxBrenda1]

No box 13 from your T4A(P) is not required which is why you do not see it in the TurboTax software.
