In short, the way to fix this up is to amend the refund based on my dad's SSN (any received refund amount needed to be listed). And I can file tax using my SSN. Will there any penalties since it is past the deadline?
@TC88 For your own tax return, if you are getting a refund there will be no penalties. If you have a payment due on your return, the IRS may bill you for penalties and interest for late filing and late payment.
If your father has a payment due on the amended return, he might have to pay a penalty and interest.
