When first create amendment to my 2022 tax, there is already refund shown up, why?

[DatBio]

I need to file an amendment to my 2022 tax. After I create the amendment file by importing my 2022 filed tax return, it already shows a $44 dollar refund. Why?

In form 1040-X, line1 for adjusted gross income, it show the original amount is higher than the correct amount.  The correct amount is what I have in my original tax filing. There is also a difference in my qualified business income deduction.  However, I have not done a thing and it already shows a difference.  I am afraid it is an error by turbotax.

There is no further instruction or form to show me how the original amount amount was calculated.

Should I be concern or just go with what turbo tax is doing?

Thanks in advance.
