It will work to separate one T3 into 2 T3 to get around the 50-50 split with your spouse, but I do not think that this is the way to approach the issue. You will be creating 2 new T3s that did not exist from your financial institution and disregarding the one that was provided by them. It may lead to other future issues when dealing with the CRA as they may ask for an explanation. For Quebec residents, the split by Turbotax was done correctly but the capital gains were not reported if you didn't put the same amount in Box 53 to match that of Box 21.
Too many workarounds are being done by the users as it would be much easier for TT to provide their fix ASAP.
