2022 Business - Sched K Line 20c demands entry but won't accept anything

I have one error.  When I run error check it highlights a "business interest expense" entry in the table of manual entries in line 20c of Sch K.  But it won't accept any value I try to enter nor will it let me delete the entry.  Below that line it says "** SEC199A INFO: SEE STMT A".  How can I get rid of this "error" so I can file my tax return?
