In 2017, I sold ESPP shares that accumulated over several years (from Late 90's to early 2000's). I originally purchased the shares at 15% less than the market price. This discount is not reflected in my taxable income from those years. TurboTax asks if I received a discount to which I entered "15%". The next question is "Did you buy all this stock at the same time" - No (multiple purchase lots. I do not have the original Form 3922 from these years so I entered the information myself (I was able to find the information on my companies web site). For "The price you paid per share" entry, I provided the actual price I paid for the shares (which includes the 15% discount). After all of the lots are entered, TurboTax tells me I have a new Cost Basis which appears to be approx 15% higher than Box 1e on the 1099-B I received. Which is the right number? Should I list the 15% discount?
