Retirement tax questions

Hi

I received 4000 $ as grad student stipend for working as summer job at local hospital. I didnt receive W2 or 1099. My college says it is stipend so not included in any 1099-T . I followed above steps and put 4000 $ under "Scholarships/Grants/Fellowships"  but still 4000 $ , doesnt show as income . I wanted to move that money to Roth IRA but Turbotax is charging me 6% penalty. What am I missing ?
