hello aspirant,

you should know that surname and the last name have the same meaning, they refer to the same name which is also called as your title,

you only have to make sure that you have mentioned the first name in place of the first name and the last name in place of last name/surname/title.

if you have done this correctly, you need not worry about anything else.

in your I'd card , it may follow a format of writing surname first and then the first name. it depends on format to format.

you need not worry about anything.

hope that helps

all the best
