The Office of Graduate Admissions typically keeps applicants' official test scores on file for a year. After you submit your application, if the scores are still on file you will see them posted to your MyStatus page https://utdirect.utexas.edu/apps/adm/mystatus/.
If you have further questions about your official GRE/TOEFL scores, please contact OGA: https://gradschool.utexas.edu/admissions/contact.
