I noticed the same problem that you are experiencing. When I talked to a person at Intuit today (March 23), they implied that the problem is because the CRA has not fully resolved its capital gains issue. I don't believe the explanation since splitting the reported amounts has nothing to do with CRA. I just did a manual override (using the F2 key) for lines 17599 and 17600 on schedule 3. I don't Netfile, so I don't care about the warning that TurboTax gives out when overriding. I'm not going to wait until Intuit decides to resolve this software bug.
