TurboTax will ask about adjustments when you are entering your stock transaction. Check the box "I have other boxes on my 1099-B to enter" to enter a wash sale amount.
An adjustment in the cost basis will show up in column G if you check the box "The cost basis is incorrect or mission on my 1099-B" and adjust the amount in Box 1e.
Hank you for your response but this is for a 1099 S so the input screens are different. And although the summary shows a place for adjustments when I go into Edit the input there is no place to enter the adjustment and select code N as the explanation to appear in a form 8949.
Keep going:
Thank you for your help but I had to actually use the CD/Download version of TurboTax to be able to do this. Im not sure why but that is what I was told.
