You may not have needed to file- In 2024, if you made less than $14,600 (and less than $400 of self-employment income), and did not have federal income taxes withheld that you'd like a refund of, then you don't need to file a federal tax return. The state rules vary, so you'll need to check your state rules to see if you're required to file a state return.
If you've determined you do need to file tax returns, you can contact your company's payroll department to help you get access to your W-2 online. If that is unsuccessful, you can request they mail a paper copy to your home address. The IRS will also assist you, you can contact the IRS Taxpayer Assistance Center here: Taxpayer Assistance Center Office Locator
