Unable to delete Miscellaneous expense

The issue is with turbo tax premier (desktop).  

To help you get on the same page, the miscellaneous expense window has this instruction:

"Here are expenses you listed on your 2020 tax return. Make any changes or deletions for 2021 and then enter your 2021 amounts."

After I followed the instruction and deleted the amount for year 2020, the same amount comes back on the next line immediately. It’s unbelievable that turbo tax actually prevents any changes or deletions (no matter what you do or how many times you tried to change or delete!  It's contrary to what the instruction says.  So, I’m stuck!

Help! Help!! Help!!!
