I accidentally claimed myself as independent but my parents claim me as a dependent, what do I have to do?

[JoceannaD]

have you and your parents already filed your returns?
If so do you mean that they claimed you and you didn't mark that "someone else can claim me as a dependent?"  And, if filed have the returns been accepted or rejected?

I accidentally checked that I can claim myself.  My parents can not e-file now because they are claiming me as a dependent.  My return has been processed and I am awaiting my return.  My understanding is that I have to amend my return once processed in order for my parents to claim me.

Correct.
