A Wage and Income Transcript from the IRS will list all W-2s and 1099s of any type that were issued to you. You can get a Wage and Income Transcript at the same link that Carl provided above for getting a Tax Return Transcript.
You can get copies of W-2s from the Social Security Administration, but they do not have 1099s. There is a fee of $86 for copies of W-2s.
