if you look at your brokerage statement or maybe even your a/c online you should see the cost of the shares you bought for $6,500 that caused a $700 wash sale as $7,200. brokers automatically adjust the basis for wash sales. be careful because when you sell these there will be a loss if sold for less than $7,200 so if you buy them again within 31 days of the sale there will be another wash sale.
