So manual manipulation is required. TurboTax should change their application so that no manual manipulation is necessary. Since that data is all there and reported on the 1099, it should be as easy as entering the data, or downloading the data in an appropriate spot, and then TT should enter the data and adjust any values they need to make. Also, when trades are numerous, like in the hundreds, it would take enormous effort to manipulate the data individual as advised. Also, typically when there are hundreds of trades, you just need to enter the summary data, and attach a brokers report of the individual trades, so in that case TT should have a way to enter the summary data of wash sales. So really this is a deficiency in TT.
