A weird bug with TT 2022 tax amendment

My 2022 total tax is X dollar and I already filed the tax return. Now I wanted to amend the child credit part. So I opened TT 2022 and double confirmed I have loaded the right .tax2022 file and TT 2022 is showing the correct information which I filed to IRS.

 

Then I clicked on the "I need to amend my 2022 tax return". Without doing anything (I didn't amend the child credit I wanted to correct) TT showed me that I should get ~$800 refund. I thought something was updated so I generated the PDF file and compared it carefully with my filed 2022 tax return.

 

The weird part is, on 1040X, the "correct amount" of my total tax is X dollar and the "original amount" is X+800 dollar and TT generated the new 1040 exactly the same as the one I filed.

 

It seems to me for some reason TT "thought" the total tax I filed is X+800 dollar instead of X dollar, which I do not know where it is from. I have double confirmed the .tax2022 is the one that I used to file the return.

 

Due to this bug I can't use TT to amend my tax 2022 return now.
