After you file

Yes I have, but the extra refund my parents would receive would be much larger than the refund I received, so they would give me back what my original refund was and I could send back what I owe on my original refund at that time, or I could charge it to a credit card if I had to send it sooner than that, or if it had to be debit/check, I could likely be able to pay it that way before their amended refund is received.
