I'm having the same problem. It appears to be a Turbotax software problem. I have several T3 entries to make. Line68140 on T936 Form remains at 0.00. When double clicking Line 61840 a box appears showing all of my T3 entries including a sum column with the correct figures. The sum of Box 52 and Box 53 on the T3 slips add up to the same value as the Box 21 values so I know there is no issue on the T3 entries. But Line 61840 remains as 0.00 and I can't override it.
