Are the 1040X columns A, B, and C supposed to be blank? I would expect them to reflect the differences for the amendment. Is this working as designed? 2018 taxes

I'm working on amending my 2018 amended return.  I received a second W-2, so I need to amend.  However, the 1040X has no entries for columns A, B, and C.  Should this auto-populate with the data from the W-2?  I could manually enter it but that doesn't seem to be working as intended.
