Since the return is accepted then you will have to wait since the IRS will adjust the response on their own end. So they will double check your response with their own records and adjust your return accordingly. There is no need to amend your return for this purpose, since IRS will adjust the return themselves including the refund amount.
However, due to this, your refund amount will be delayed for a longer period since IRS will be making the adjustments. However, as mentioned above, no need to amend your return if this was the only issue you were trying to edit.
