Unamortized Loan Fee Write-Off

A real estate partnership refinanced a loan in 2019.  The prior loan had an unamortized loan fee balance.  I "sold" the asset, but the Federal Asset Entry Worksheet, under the Dispositions section is highlighting the box, "Asset Sales Price" as red.  The entry is -0-, as it should be.  What am I doing wrong?  Or, what is the proper way to write-off unamortized loan fees?  Thank you.  Dan
