wash sale on a closed position in same year (1099-B linked)

[samschaperow]

How do I know if the two wash sale amounts that were disallowed were added into the cost basis of the new transactions? If not added in, and if Turbotax doesn't take care of it for me after important the file, how do I manually make changes in Turbotax to not lose on deduction amounts?

Two 1099-B screenshots (no need to sign up for dropbox, as you can just view the links w/o an account):

" disallowed were added into the cost basis of the new transactions"

IRS requires the broker to track this information , so your loss will be reclaimed on sale of the triggering buy transaction, if you do not incurr another wash sale when you sell it.

No action should be needed on your part.

Otherwise:

If reported basis is wrong,

For Box A or D, leave basis as reported, use Code "B" and put an adjustment in col(g).
If you check the box indicating you have other boxes on your 1099-B to enter, TurboTax will do it this way.
