My daughter and I did our taxes on separate dates. She incorrectly stated no one could claim her as a dependent. When I did my taxes and claimed her, it was rejected.

Because she selected that I couldn't claim her when I can, my return says I owe $500. She earned less than $4K and was at home most of the year (more than 8 months). She already received her return. What should I do? Just pay the $500?
