Desktop file another return

I’m going to file another return on my Windows program.   Her Mac is too old to install Turbo Tax.   Hopefully I can copy the .tax2024 file from Mac to my laptop and transfer it.   Hope I don’t have the Mac transfer problems that a lot of people are having.

 

Then should I or do I need to go to File - Sign In to her account?   Or just use her account when filing and paying for state efile?   And for email?   I don’t remember does it ask for the email at the end when you file.  I don’t want to get her emails.   

 

Also we import her 1099 forms.  I don’t import any of mine.  So to import I’ve read you now have to sign into your Turbo Tax Online account?  Do I sign into hers at that point?  Will it ask to sign in then?
