Updated reply: Found some prior posts from 2022 with the same issue that said to save the spouses return as a PDF and then you can print from outside Turbotax. I just tried it, saved the spouses return (again as I'd already done that) as a PDF and then I tried selecting the print option from within Turbotax and it printed the correct spouse's return this time. Good luck! Hope that works for you.
I'm having the exact same issue. Tried closing and reopening the program and toggling back and forth between both returns and no luck.
