Where the hack do I get the symbol for my favorite stocks?!

The easiest way to get the symbol for your stock is to open finance.yahoo.com and use the search field on the top. You'll find the symbol either in the search preview or in the result page's URL (i.e. https://finance.yahoo.com/quote/BMW.DE?p=BMW.DE where BMW.DE would be the symbol).
