After you file

I amended my taxes in March using Turbo tax. It's the first time I've ever had to amend my taxes so I'm not sure if I missed a step or what. I have read of people having to mail letters in. I haven't sent anything in the mail for the simple fact that I thought the amending process I went through on turbo tax did it for me. It's now June 29th and it says it's not available to check. Just need to know where to go from here.
