Am I required to enter asset loss from K-1 (box 10) in TT if it is not reducing my tax liability? It is for some reason reducing my QBI 20% tax break

Yes.  You need to report the information exactly as reported on the K-1.  Remember, the business has already filed the K-1 information with IRS and you do not want to reflect different information on your personal return.
