@sjrcpa:

In live conversations, I frequently drop movie quotes, so much so that it gets annoying. 

If you allowed me, I'd quote Tom Hanks in You've Got Mail, and say, "Don't cry, Shopgirl."  

You came in very close.  The so-called "my official answer" is this:

The basis info provided in many brokerage statements is based on the adjusted basis.

In my question, as phrased, the mistake I made in TurboTax was that I didn't enter the wash sale info, which is typically included on the brokerage statement. 

Actually, sometimes, if you compare 

(1) Total Proceeds - Total Basis

to

(2) Realized Gain/Loss

on the statement, you would find a difference, which is = the total Wash Sale.

Of course, it all depends on how the reporting of the brokerage statement. 

As I said, the level of the Asker's sophistication was in consistent with the $701K loss..  My first impression of the Asker's post.

Just projecting my experience to the Asker's $701K Loss. 

Shop Talk.  Thus, "Don't cry, Shopgirl."
