How do I adjust food amounts?

Hi. I just joined today and started putting in what I had for breakfast. I had a scrambled egg (1 fresh egg with 1 tbsp milk). But, when I went to look it up, there must have been 50 entries listed under egg, and I could not find just a regular scrambled egg with milk. When I put in 1 "dry" (not even sure what that means), it would not let me select anything less than 1 cup....I do not think one egg equals one cup. Anyway, it came up with 494 calories, which is way more than 1 scrambled is (I googled it and it is 91 calories). It seems like I can't "edit" any of the amounts. There is a big difference between 91 and 494 for the same food. Am I missing something?:(
