Can I bring up a Schedule C form?

Are you referring to a capital loss carryover on Schedule D?  Routinely only $3,000 of such a loss can be offset against the current year’s income.  To access this information, follow these steps.

• Down the left side of the screen, click on Federal.
• Across the top of the screen, scroll down to Capital Loss Carryover.
• Click on Edit/Add to the right.

Please stick to one post.

Any business losses on Schedule C would have been reported many years ago, with no carryover.

Your comment about a $3000 loss implies a capital loss, but that is NOT a loss from a business.

As I said in your other post, you need to provide details about EXACTLY what this loss was from, as your questions don't make sense.
