Since you have already filed your return you will have to wait until the IRS "Accepts", or "Rejects" your return.
If your return is "Accepted" you will have to amend your return and correct any errors. If your return is "Rejected", you can fix the errors and resubmit your tax return.
This may impact your State Return as well. You can "Amend" the state with your Federal Return.
