After you file

@ThaddeusP  Yikes,you didn't need to amend for that.   The IRS will automatically adjust your original return if you got the wrong amount on line 30 or 28.   If fact you should not amend until the first return if fully processed and you got the first refund or paid the tax due.   

The IRS is taking a long time this year. Keep waiting.  It might be 6 months or more.
