USA K1 loss 2017 (box 1) larger than total income for 2017

[ps21212]

If in 2017, a K1 has a large box 1 loss (active participation). Let's call it 200K loss. If other income in 2017 adds up to 100K, then only half of that 200K loss is utilized. Are there steps can be taken to utilize the remaining loss in 2018 or carry back the loss to a prior year, or is 100K of that 200K essentially wasted?

If there is basis to absorb the loss it should cause a net operating loss that can be carried back or forward. Starting in 2018 no more carryback.
