Here is how to get there: While inside the software and working on your return, type carryover in the Search at the top of the screen (you may see a magnifying glass there). There will be a popup that says Jump to carryover. Select that to get to the general area.
Here's how capital losses work: Short-term losses are first deducted against short-term gains, and long-term losses are deducted against long-term gains. Net losses of either type can then be deducted against the other kind of gain.
If the net gain is short-term, then you pay short-term capital gains rates. If the net gain is long-term, you pay long-term capital gains on that net.
If someone had an overall net capital loss for the year, they can deduct up to $3,000 of that loss against other kinds of income, including your salary and interest income. The remainder will carry forward to future years.
