ESPP tax question

I sold ESPP shares for the first time in 2021. These are qualifying shares purchased in the 1990s, and all sold with long-term gain. Situation 3 in this article is exactly my situation:

I don't recall if the discount of these shares were reported on my W-2 forms for the years they were acquired. These shares were not recorded as ESPP at the brokerage. After the sale, they sent me a 1099-B form with Dates Acquired and Cost Basis for all the shares sold. I have no record of 3922 or W2 forms from the employer, as mentioned in this video:

I will be using TurboTax Premier for the 2021 filing. Questions:

 

- Will TurboTax guide me through how to enter all the information, including the shares' Offering and Exercise dates and prices, etc. to calculate the company discount?

 

- Will the company discount be added to the 1099-B cost basis?

 

Thanks in advance.
