Are you using the Online version or the Desktop program? Will they be using the same computer?
If you use the Desktop program each return is saved on that computer in a separate file ending in .tax2025. Your data is not kept in the program. So someone using the program could open any return. You could copy your return to a flash drive or somewhere else and then delete it from the computer. Or you can put a password on a file. Go up to File-Password.
