How do I share a return between desktop/laptop computers?

I have the return ".tax2024" on a google shared drive.

 

I have two computer with TT Desktop installed and licensed.

 

On the first computer,  I can open the file fine.

 

One the second computer it asks me for a document password.  I did not apply a password to this file and have no idea what it would be.

 

 No, I will not be trying to open on both computers at the same time, but want to be able to switch back and forth as needed.
