I have filled out the T4A(OAS) slip with the amount shown on Box 21 (all other boxes are empty). Saved it. And I can see that amount appearing on T1 General, Line 14600. When I tried to send NetFile, an error message says "I have not reported an amount for Old Age Security" but when I clicked the FIX button, it pops up the T4A(OAS) slip which does have the amount that I entered earlier. Why ?
The system won't let me send NetFile.
