Actually, the person who claimed you as a dependent would be entitled to the third stimulus payment. I would suggest asking your parents if they did indeed claim you as a dependent or not first. If they did, they will receive the stimulus payment for you.
How will the 3rd stimulus affect me
If they did not, then I'm assuming you reported that they did not claim you on your return and if so, the third stimulus payment should be sent to you assuming you meet all of the requirements based upon your 2020 income tax return.
You can go onto the IRS website using the link below to track your payment to see if it has been issued or not.
