Turbo Tax doesn't have your W2.  Only the info you entered from it.    You have to get another copy from the employer or from Social Security

How to get a W2 copy from SSA

https://faq.ssa.gov/en-us/Topic/article/KA-02501

Or If you just need the information from your W-2, but not an actual copy, you can get a Wage and Income Transcript from the IRS for free. This will contain the information from all the W-2s that were sent to the IRS by your employers. However, it does not include the state and local information (boxes 15 - 20). Go to the following link to get a transcript. You want a Wage and Income Transcript, not a Tax Return Transcript.
