" Is this the correct way to report it? "
No. Use the installment sales method for the ENTIRE transaction. Your proceeds will include the 2019 and 2020 amounts and you'll you'll declare only a portion of your basis against only a portion of the proceeds.
"The total for each of these shows as 0. Is this correct?"
Well, now you're going to eliminate the 1099-B entry and enter the entire sale using the installment method.
Assuming this was a disqualifying disposition and the per share selling price was used as the "fair market value" of the stock for purposes of the calculation of compensation, then I'd expect that you'd have no gain here. All the "income" has been recognized as compensation.
Question: Does the compensation reported on the W-2 jibe with ALL the stock being sold?
