I have been tying for 5 days to input my 1098T and there seems to be a glitch that wont let me put in the tuition costs. Am I alone on this ?

No. There are a lot of complaints and a recent software update has been helpful.

 

Go through the entire education interview until you reach a scree titled "Your Education Expenses Summary".  Click edit next to the student's name. That should take you to a screen “Here’s your Education Summary”. Click edit next to the section you want to change; tuition, in your case.

Details:

To enter your Form 1098-T information (even when TurboTax thinks it has already been entered and is showing $0), go through the entire education expenses section of your return until you reach the screen titled “Your Education Expenses Summary”, then follow these steps:

• Click Edit next to the student name.
• On the screen titled “Here’s your Education Summary”, click Edit beside Tuition.
• Enter the information from your Form 1098-T.

 

To go directly to the Education section of your return, use these steps:

• On the top row of the TurboTax online screen, click on Search (or for CD/downloaded TurboTax locate the search box in the upper right corner)
• This opens a box where you can type in “education” (be sure to enter exactly as shown here) and click the magnifying glass (or for CD/downloaded TurboTax, click Find)
• The search results will give you an option to “Jump to education”
• Click on the blue “Jump to education” link

Here it is 13 July 2020, and I am having the same issue. The software will not let me enter the information on the 1098-T. It actually says I already entered it yet it never gave me the prompt to do so. I can't edit it either. It has a "zero" listed and will not let me edit and enter the information. I guess I'm going to have to ask for an extension unfortunately.

See answer above.
