Please consult a CPA or certified tax professional, dont go to H&R Block, paying a good professional CPA thats reputable can save you more than you think. If you dont know one or know anyone that knows one you can simply look online in your area and then call and ask the CPA a few tax questions relating to stocks that you know the answer to and see if they know it off the top of their head, if they dont have time for you or dont know then that means they arent worth your time and call another. You may even possibly call them and ask them how a wash sales works, this should be free quick advice, some will try to make you "come in" to see them, once again if its just a few questions that take less than 5 mins and they cant answer for free its not worth your time and move on to the next CPA/Tax Professional... Call about 20 of them and score them on a piece of paper, look up their reviews online as well. For basic taxes with stocks should be around $150-$250 fair price... if you have property and other assets and businesses or 1099s it may be more. You may think calling 20 CPA is extreme, but this is your hard earned money, and if you make a significant amount of money you should be trying to save a much as possible and need a excellent CPA... only you can protect and help save yourself money, however you have to put in the time to do so.
Do not take the following as advice however my interpretation is Tax lot and tax method when you signed up can make a difference, such as first in first out or first in last out , etc... If your accounting does basic total capital gains along with method short term holds (less than 12 months) it wont really matter, if you are trying to account for a asset/security in which you held over 12 months to get the tax break then wash sale would matter and the tax method you chose would matter. It can get more complicated, but this covers what i assume most people get confused/worried about. Once again this is not tax advice, this is simply my interpretation, so i advise you to seek a professional.
