My s-corp (in the trade/construction industry) has a NOL in 2018. Can the NOL be used as a carryback under the new tax rules?

I have a s-corp (100% owned//sole shareholder) that works in the construction/trade industry.  In 2018 there is a NOL of approximately $7,000.  Of course since I'm the sole owner, my K1 shows the full NOL.  Also, I stopped the business (ceased operations) in 2018 (but have yet to file the dissolution).  Can I use the NOL as a carryback still under the new tax rules?  I'm aware that I will not be able to carry forward as the business is no longer in business.  Can somebody shed some light on my question?
