Where can I add my parent's taxable income on my taxes? I had the page up for a second but then I lost it, so I need to add this info but I can't.

I was just waiting to get my mom's taxable income but then I refreshed the page on accident and now I cannot find where to put that information anymore. I know I need to add it in there but I can't get back to that page to add my parent's taxable income since I was claimed as a dependent.
