Amend 2019 return (accepted) in downloaded edition (mac)

I have followed the directions for making a copy of my original 2019 return and saved it as "amended".  When I open it, I cannot find any tab/button for amending, or the 1040x form.  The online forums I've read all sugest there is a button or tab, but I think this is for the online version, not the desktop version.  How do I proceed with amending my accepted return in the desktop version?

I have read this multiple times, but at step 4 I cannot find a tab/link to amend or "jump to".  I believe this only applies to the online version of turbotax, not the downloaded version (which I stated in my original post).

 

Where, in the program, do I find this "amend" tab/link?

 

Thanks

After you file

Start TurboTax Desktop (Windows).

Click File->Open in the MENU

 

The button to Amend a Filed Return should be there.
