I worked in another state for only the month of january

Here is what the IRS says:

Most taxpayers got their Form W-2, Wage and Tax Statement, by the end of January. Taxpayers need their W-2s to file an accurate tax returns, as the form shows an employee’s income and taxes withheld for the year.

Taxpayers who haven’t received their W-2 by the end of February should:

• Contact their Employer. Taxpayers should ask their current or former employer for a copy of their W-2. Be sure the employer has the correct address.
   
• Call the IRS. Taxpayers who are unable to get a copy from their employer by the end of February may call the IRS at 1-800-829-1040 for a substitute W-2. The IRS will send a letter to the employer on taxpayers’ behalf. When they call, taxpayers need their:
  • Name, address, Social Security number and phone number.
  • Employer’s name, address and phone number.
  • Employment dates.
  • Estimate of wages and federal income tax withheld in 2017. Use a final pay stub for these amounts.
     
• File on Time. Taxpayers should file their tax return by the due date. If they still haven’t received their W-2, they should use Form 4852, Substitute for Form W-2, Wage and Tax Statement. They should estimate their wages and taxes withheld as best as possible.
