Mail-in voting by the numbers?

Is there any place on the internet where you can see how many people voted for Joe Biden by mail-in voting and how many people voted for Biden in person and the same for Trump in the last Presidential election? Also, I would like to see the stats for this coming presidential election. If the stats show that Democrats vote 80% by Mail-in and the Patriots vote 20% by mail-in -then something fishy is going on...there are so many ways you can cheat on mail-in voting...
