If you are using TurboTax Online, there is no way to directly access the forms. If you need to change Line 323 – Your tuition, education, and textbook amounts then you’ll have to go through the Students section of the TurboTax interview and make any changes through there. You can use the Find tool in the top right to search for Students, select it from the list and click go. Check off anything that applies to you and click Continue to go through the pages.
