Not sure what you mean by getting back the "full amount"----if you have a W-2, you can get a refund from box 2 and/or box 17 of the W-2 -- federal and state tax withheld. You will not ever get back the amounts that were withheld for Social Security or Medicare. That is not different for minors.
If you can be claimed as a dependent, then it will be very important for you to say on your own tax return that someone else can claim you as a dependent. If you are under the age of 19--- or under the age of 24 if you are a full-time student---you can still be claimed as a dependent by your parents. In My Info it will ask if you can be claimed by someone else. You must say yes.
