If you can be claimed as a dependent on your father's return then you need to amend your own return to change the way you answered the question in MY INFO that asked if someone else can claim you. But Dad does not need to wait for you to amend. Your SSN is already in the system now, and Dad cannot e-file; he will have to file his return that claims you as a dependent by mail. Make sure you tell him to go ahead and file his return as soon as he has it ready to put in an envelope.
To amend your return:
Wait until your original return has been fully processed before you amend, and make sure you have saved a pdf of the original return before you amend. (If you do not save it as a pdf, the amended return will overwrite the original, and the original will be lost forever)

Do not expect quick results from amending. It can take four months or more for the IRS to process an amended return.
