Troubleshooting

I've been using turbo tax online for 3 years. Last year I wanted to use my tuition tax credit for the school I attended in August of 2021- May 2022. I have a T2202 for the August to december credit. When I went to use it on turbotax under the student tab, I filled out all the information, the school I attended, the dates and the amount but on the next screen, it said I wasn't eligible because I had to be between 26-65 to use the credit so I transferred the credit to my mom. This year I wanted to use the other half and the same error message came up that I can't use my tuition tax credit. When I went to check the federal government site, it says you can use it as longas your 16. I'm 20 years old. Why am I getting this message and what can I do to fix it? I have a T2202
