Retirement tax questions

I filed my taxes already. I decided to file my tuition this year for the first time. I used my 1098-T from the university and entered the amount from box 1 ($2512.70). This brought my return up to $3,115, stating that I would be receiving about $2100 in federal credits. I recently received a 1099-Q from my Florida prepaid tuition plan. Do I need to amend my submitted tax return when I get my refund? I do not want to be penalized next year for this mistake. Thank you
