I didn't realize I could claim head of household eventhough I do not claim my son this year. Can I amend my return?

[htare]

My son's father and I alternate years for claiming our son.  It was brought to my attention this year that I am still able to claim head of household.  I didn't know that until after I filed today.  Am I able to go in and amend it before it is filed?

Once your return is processed you can amend it for Head of Household, EIC and, if appropriate the child and dependent care credit.

Am I able to go in and amend it before it is filed?

Sorry, but no.  (On the other hand, if the IRS rejects it, you can correct and resubmit without amending.)
