How is that done?  The capital loss for my spouse needs to be entered in for her only as I can not use her prior loss against my gains and it needs to be tracked separately for her use only going forward.  The capital loss carryover worksheet has a check box for Taxpayer, Spouse or Joint.  I need one established for "spouse".  I have one established now for Taxpayer for me.  Maybe If I changed my existing Cap loss carry over sheet to joint it would give me more options.

To be clear here,  this is a new marriage and my spouses capital loss carryover is prior to our marriage

Or do I have it wrong and we can use her old Cap losses for us since we file jointly now even though she incurred them when we were not married?

That is my theory. I am double checking to be sure.

 Both TP and SP loss ends up on the same worksheet, so in the end, $3K of the loss will end up on sch D.

I used the override function (right click and select override) to edit the cap loss carryover amount from the prior year in this years combined worksheet and it looks correct now.  Also unchecked the "taxpayer" box and checked the "jointly" box.

Good!
