If you have type it mistakenly, you should have changed it in the correction window session of TS EAMCET which was from 2/07/2021-12/07/2021. Now as you haven't done it, then its not possible to change now. Now if you have put such things mistakenly then there can be problems in counselling as it adds to discrepancy of information. Now if you have filled all the other things correctly then there are less chances of problem, but yeah! there are certain possibility of problems during counselling.

Another way can be that you can contact the official number of TS EAMCET and get your problem discussed. If there are any ways then they will guide you out.
