You are wrong here.
"Assuming vested RSU is 100 shares, 40 of 100 shares were withheld for tax. Also assuming $15 per share is the market fair value on vested date. Therefore the total proceeds is 100x$15=$1500."
The vesting creates $1,500 of compensation, not $1,500 of proceeds from a security sale.
If you sell all the stock on the same day as the vesting then something close to that $1,500, (net of broker fees) could also be proceeds ,but you are talking about two completely distinct activities here.
- Vesting creates compensation
- Selling stock (at any time) creates proceeds, (and gain or loss)
I'm guessing that you have a "same day" sale here, (or maybe two "same day" sales, one the the stock sold "for taxes" and one for the remainder of the stock you decided to sell "for cash"), and you've gotten tangled up in the RSU "guided" interview for the sale(s). But same day sales typically create a small loss due to selling commissions and fees.
Here is how to get out of this mess.
- Delete the trade(s) that you've entered. Don't attempt to edit or modify them.
- Enter the trade(s) using the non-guided basic "1099-B" entry form exactly as the 1099-B(s) received from the broker reads.
- Then use the mechanism available in TurboTax to "correct" the basis from the $0 shown on the broker's 1099-B to the correct cost basis of $15 per share.
For step 3., in the desktop versions of TurboTax you'd click the blue "I'll enter additional info on my own" button below the 1099-B entry form and on the new page that that comes up enter the correct basis in the "Corrected basis" box. I assume the online version has something similar.
