No, you will not get a 1099 for the stimulus payment. It is not taxable income. You will get Notice 1444 for the first stimulus payment and Notice 1444-B for the second stimulus payment. But if you don't have the notices it doesn't matter, as long as know the exact amount of each payment that you received. At the beginning of the Federal Review in TurboTax it will ask you whether you received a stimulus payment, and you will have to enter the amounts.
