That does not even make sense. Why did you file an amended return to change a job title? The IRS does not use "occupation" for anything except statistical purposes. It has no effect at all on your tax due or refund. It is taking at least six months for the IRS to process amended returns. No predictions as to what if anything they will do with a frivolous amended return.
You did WHAT ???? A job title correction ONLY ??? You did not need to amend for that so if there were no changes in Column B the IRS will most likely ignore the return and/or shred it.
No change in tax is not unusual if you are correcting or adding missing forms or schedules.
IRS can't shred your amended tax return; Form 1040-X becomes your new tax return.
It will have to go through review along with all the others.
