They are required to give you the form or make it available online by Jan 31 as they withheld taxes from your payment. There should be some kind of documentation on the website now that will allow you to gather the information you need to get credit for the taxes withheld. The IRS does not start accepting returns until Feb 12th. If you don't get the document, look in the payment history on their website. Even though you returned the money, they should still show the payments with the amounts withheld for income taxes. As long as you have the amounts, you will be able to claim the credit for the taxes paid, even if you don't get the 1099-G.
