You should contact Kroger if you don't receive it soon. However, if you were paid W-2 wages from Kroger during tax year 2017, they should issue your tax document. They do have until January 31, 2018 to mail your W-2.
You may also be able to import your tax document from Kroger, if they partner with TurboTax for this feature. You will need to know the employer's EIN.
See the information below for importing your W-2 into the TurboTax program.
