T3/Schedule 3 Capital gains

Yes.  I've written about this and other related errors (T3 capital gains and prorations) multiple times.

The issue is being looked into.

As a workaround, you can enter the T3 on both spouse's return, but manually calculate the split and set the "Your Percentage" value to 100% for each. The "Your Percentage" value just tell TurboTax to do the split, it's not transmitted to the CRA.

Yes ... rather obvious ... too many slips to deal with individual return manual calculations which is a primary reason I bought TurboTax in the first place.
