When reviewing my return, I noticed that only a few of the securities that I sold were mis-formatted on the Capital Assets Sales Worksheets.
These were downloaded 1099-Bs from Schwab. The description of the asset was cut to only included the part after the ampersand. For example "100.0 Vanguard S&P 500 ETF" was converted to "P 500 ETF". I have a few like that and they seem to follow the same pattern. Can also assume that a web download may face quoting issues with an ampersand.
