I ran into this on my spousal return, but not on mine, even though they have the same numbers on lines 68140 and 17600.
WE both have 2 T3 slips. (Since the T3 splitting wasn't working for capital gains., I entered 2 values cut in half for each return for one of the slips.)
For BOTH my spousal, and mine, indeed, the number for capital gains on line 68140 was 31.01 lower than the number for line 17600. ($12, 793 .46 on 68140, instead of 12,824.47, which is the correct sum of the T3s on line 17600.
Could it have something to do with a return of capital number entered on line 42? Unfortunately the difference there is not 31.01.
SO pretty odd that my return was accepted with that apparent error, but hers was not. I tried 2x.
