Per your instructions, I switch to the FORMS mode and made sure the 1040 was the same as what was originally filed. I then started the amendment process. When I started on the amendment copy, the first thing I did was to check "2019"as the return calendar year in 1040-X at the top of the form. This caused the numbers in 1040-X, Column A, B & C to automatically populate. Even though I made no other changes, Column A still did not match the numbers that I originally filed. However, the numbers in Column C do match correctly. And Column B shows the differences.
