This issue is usually from the screen resolution. This is a work around for now- When you get the white box, move your cursor around. At some point around the left side in the middle, your cursor will change from an arrow to what you normally get over a dialogue box. Click here and type in the licence code. Then move to the bottom right and your cursor will change again when you get over the “ok” button. Click on that area. It should get you in.
Thank you for choosing TurboTax.
