while it may not be germane to this situation, the washsale triggers all purchase transactions that occur 30 days either side of a loss transaction, so you have to look 30 days prior, the day of, and 30 days after the transaction or 61 days.
example:
1) I buy 100 shares of X on May 1 at $10
2) I buy 100 more shares of X on May 10 at $15
3) I sell the May 10 lot (100 shares) at $11 per share on May 25
that is a wash sale loss situation - because I sold shares at a loss but purchased a similar security within 30 days on either side of the loss transaction, which I did because of the May 1 transaction, I have a wash sale loss of $400 on the May 25th sale and that $400 gets added to the cost basis of my May 1 transaction.
I could have decided to sell the May 1 lot instead of the May 10 lot. In that case, I have a reportable gain of $100.
