Looks like an elephant snail. The one I have sometimes shows a white part on the top, but most of the time it looks just like that.

I have no idea where it came from,, haven't added anything to my tank recently except a few frags on plugs and this thing is big,, the size of a silver dollar or a little bigger,, good for tank I assume?

Yes it doesn't bother anything. It's most likely been in your tank for a while. I will see mine at night for two or three days and then won't see him again for a month or two.
