Hi, I had filed my taxes online e-filing and because on form 8949 I didn't list all my security transactions as single transactions along with the wash sales, I was told I need to physically mail in Form 8453. So I am going to do that with a 1099-B summary statement. So this might sound silly, but it is safe that my 1099-B includes my account # on the statement or should I blot that out? Is it risking anything?
