Amending 2022 return, I may have messed up

I know that I forgot to add my new vehicle expense to my 2022 tax return.  we sold our old car and got a new one and are now using that new one for my wife's business.  I remembered to enter the miles for the old car, but forgot to enter the new car, and I've already e-filed.

 

to understand the impact I opened up my desktop turbotax and quickly made the change to see that it is about a $800 difference in the bottom line for state and federal...  I then closed, but didn't save the file.

 

However, when I open the file back up and say that I want to start an amended return it seems to have these changes already in it.  Instead of starting with $0 in the refund status boxes it has $700ish in federal and $100ish in state.  

 

Then when I go a little further it says that it is not detecting any differences between my filed and amended return...?  Is there a way to load and start from the file that I actually filed?  or maybe I need to un-edit this file, start the amendment and then re-edit?  I should be able to do that.

 

Thanks
