Amending

I recently filed my 2022 tax return and discovered that I was charged an underpayment penalty, even though I paid more than 100% of my tax liability from the previous year. To correct this, I am attempting to amend my return by importing my original return into TurboTax. However, I noticed that after importing the return without making any changes, TurboTax is showing a $322 refund. Upon further examination, I found that Column A in the 1040X form contains an incorrect number, while Column C has the correct number from my original return. I am wondering if this is a bug in TurboTax
