How do I remove a state from a .tax2022 file so I can open on another computer?

I'm trying to help my mother with her TurboTax 2022 file.  She erroneously entered a state even though she doesn't need to file a state return.  I use a different state.  My copy of TurboTax desktop won't open her .tax2022 file without downloading the state she selected.  We tried to follow these instructions to remove the state from her return but the "remove state return" option is greyed out.

 

So how do we get her .tax2022 file so I can load it on my computer without downloading that state?
