If you need to correct an address and NOTHING else then you mail in a form 8822 and NOT a 1040X.

Amended returns are currently taking 6-8 months to process.
You can check the status of your amended return here but allow at least 6 weeks after filing for it to show up:https://www.irs.gov/filing/wheres-my-amended-return
Thanks. Mine showed after only 3 weeks though.
