Hey!

In which form you did that please mention it and be more specific while asking question from next time it will help for better resolving your query.

But In this case as you say that you did this than try to edit the form/application or if the editing is not possible in your case try to fill it again if there is no issue in that or you can also contact to the authority and mention your mistake that you had done may be you will get a reply from there side.

Hope this helps!

Good luck!
