As I mentioned before, generally a Schedule C will be fully "At-Risk" which would mean the losses are used, not carried over. But you can check the details for "At-Risk Amounts" in Publication 925.

Assuming you were fully "At-Risk", there is carryover. If the losses were large, you may consider amending prior tax returns to use the losses.
