My current game:

World League 2011 R1: Team USA Southwest vs. Team Turkey - Board 25

Has my my 11th move as Qxc7 and I didn't input this move, how did this happen?  I'm sure there is not much you can do about this, but I would like to know for future reference so if there is anything I did I can keep from doing it in the future.  My game is hopelessly lost now.

The link you posted leads to a 'post deleted', which game is it ?

from what i can tell your opponent played Qxc7

You probably need to raise a ticket for this and send it directly to chess.com.

For future reference, the following type of data would probably be relevant:

Which browser were you using?

Were you playing on a PC - or a mobile device?

Which type of mouse do you have?

Do you have a wireless connection to the internet?

Did you click NEAR your queen?

Did you make a DIFFERENT move with your queen?

Did you open the Analysis Board?

Did you see the queen move happen - or did it occur while the game window was closed?

Should lead to the game.

I had the analysis board open on my phone last, but I didn't move my queen at all.  I was merely looking at where she should go.  Maybe a pocket move by accident?
