No, you entered the forms incorrectly. The statements you got from the casinos WERE W-2G forms. Because you did not enter them as if they were W-2G's, but only entered them as other income, the IRS computer thinks that you ignored all of the W-2G forms that you actually received. You will need to write a letter to the IRS explaining what you did, and that you already reported the income but, just differently than they expected.
