I have never sold any ESPP, only RSUs, but where do I get this information in the screenshot from?

I do have a 1099-B, Tax supplement doc, and obviously my W-2, and the only other doc I have is form 3922 which is focused on ESPP (Not sure what 'Statement from your employer' means as shown below. I obviously have all the fields filled in on the first page of the sale (description date acquired, date sold, cost basis which is $0 for RSUs, and the code). This screen below came up after clicking 'Yes' to the question "Was this a sale of employee stock?' - Now, as I said, I did not sell any 'plan' based shares like ESPP, and the only transactions I have are the sell-to-cover for my RSUs and some of the vested RSUs I sold. 

Should I just click 'No, this is not employee stock' and move to the less common options and correct my cost basis from the supplement doc provided by my broker? 

Please help me understand this as I filed 2021 taxes and chose the 'No' option then corrected my cost basis and Form 8949 had the correct entries so not sure if the 'Yes' or the 'No' makes any difference to the IRS.

RSUs are pretty straight forward; therefore, I recommend you enter your transactions without indicating you are reporting the sale of company stock.  Indicating that is company stock has no impact on what's reported to the IRS.  It only affects what screens and questions you get in the TurboTax interview.  When RSUs vest (the stock is delivered) the entire amount is ordinary income.  Your employer must collect payroll taxes, or sell shares to pay it.  Since you are taxed on the entire amount, you basis is the amount that is added to your W-2 which you are taxed on.  If you retain the stock, any gains on the sale will be short term if you hold the stock one year or less, and long term if you hold it more than one year.

If your sales are from the same lot of RSUs, the cost basis (per share) and acquisition date will be the same for both transactions.  The proceeds and sales date will be whatever is reported on the 1099-B.
