Based on advice from other Turbotax users, I changed the display resolution (search Display Settings in Windows) to a lower resolution such as 800 x 600. This will allow the box you need to click on to appear. You will need to change the display resolution back to the original setting once you have completed this step. My understanding is this is a Windows 10 incompatibility issue for Turbotax, but this is based on other user comments.
