Don't panic. The reason the IRS is asking you to verify your identity is most likely to protect you against identity theft, since it is your first time filing. Don't interpret it as having made any mistake or any type of wrongdoing.
Since these are items that you will need to have in general, you can advise the IRS that you will provide what they ask for in as timely a manner as you can, and explain that you need to obtain them. While you are waiting for the letter and the appointment, Here are links that can help you:
