I need my w2 for from 2021 from cracker barrel

As you indicated, the best way is to Contact your employer  Contact your employer to see if the W-2 has ben sent, and request a duplicate.

• You can contact them by phone.
• Walk in and talk to a manager.
• You ,ay be able to get it online.

1. Contact the IRS:  If you could not get it from your employer you can contact the IRS.
   1. You can call toll-free at 1-800-829-1040 or contact a Taxpayer Assistance Center Local IRS Office.
   2. You must provide your name, address, city and state (including zip code), Social Security Number, phone number, and have the following information ready to provide:
   3. Employer’s name, address, city and state (including zip code), and phone number
   4. Dates of employment
   5. An estimate of the wages you earned, the federal income tax withheld, and when you worked for that employer during the tax year. The estimate should be based on year-to-date information from your final pay stub or leave-and-earnings statement, if possible.
2. If you have not received your Form W-2 by the due date and have completed steps 1 and 2, you may use Form 4852 Substitute for Form W-2, Wage and Tax Statement. Attach Form 4852 to the return, estimating income and withholding taxes as accurately as possible. There may be a delay in any refund due while the information is verified.
3. File your return You still must file your tax return or request an extension.
4. File a Form 1040-X If this happens to get the W-2 and it is different, you must amend your return by filing a Form 1040-X Amended U.S. Individual Income Tax Return.

Please see this TurboTax article on What To Do If You Haven't Received a W-2.

TurboTax (TT) does not have your W-2 (in either the on-line or desk top versions). However, it does have a "facsimile", if you typed in (or imported) your W-2 when you prepared your return. If all you need is the information from your W-2, you can get that from the facsimile (W-2 worksheet), found in the list of forms. Every bit of information on your actual W-2 will be on the TT worksheet. Whether whomever you need to show your W-2 to will accept the worksheet instead; you'll have to ask them.
