Since you have already filed your return, you'll need to wait for your tax return to either be rejected or accepted, if it is rejected you can make any corrections or add any information that you need to add, correct any other errors on the return and resubmit it.
If it is accepted, you will need to amend your return to make any corrections or add any information that you did not include on your original return. You cannot e-file an amended return as this cannot be filed. You will need to print and mail the amended return in order to file it.
