Can a client (on their personal tax return) carry over a loss that was not needed if the loss was from their K-1 S-Corp?

If so, the system seems to not being do this automatically...so how do I prompt this carry over?

If the loss was able to used on a particular year's return it is used, whether it is "needed" or not. No picking and choosing when to use it.
