How do I copy my return from desktop to laptop?

I have TT 2023 on both my desktop and laptop.  I did my taxes on the desktop and now want to have the file on the laptop.  I was able to put the return on the laptop but it has no information other than the standard deduction.  It has no Federal or State dollars listed int the boxes at the top of the page.  I tried to copy but could not.  Looked for an import function but couldn't find it either.  
Can someone tell me how to put the full return on my laptop?
