That is correct. Be sure to prepare your state return as well, provided you live in a state that has a state income tax.
Also, when you mail in your prepared amended tax return, you need to attach any documents showing tax withheld, such as your W-2’s (that you mentioned you have) or any 1099’s. It's also a good idea to use a mailing service that will track it, such as UPS or certified USPS. This way you will know when the IRS has received the return.
You can contact the IRS directly for more information regarding the status of your amended return once you have filed it.
