amended return 1040-x

I filed my 1040 for 2021 then I found out that I have information from a K-1 so I need to amend my 2021 return.  When I bring up the year 2021 1040 form the orginal information is correct but when I look at the 1040-X form  (before I have done any changes) Turbo Tax put my original amounts in column C which is for the "Correct Amount".  From what I read the orginal amounts should be in column A "Original Amounts"

 

Do you know why this is happening to me?
