If your status says "unavailable"" on the Get My Payment website, then it is likely that the direct deposit of your stimulus payment was affected by the recent IRS processing error. You can expect the IRS to make a second attempt within the next few days.
If you have not received your payment by January 15, 2021, AND your status remains "unavailable" at Get My Payment, then you will claim your credit when you file your 2020 tax return.
We know that this stimulus is important to you and your family and we are committed to getting you your money. You can find the most up to date information at IRS Updates on the Second Stimulus and TurboTax updates on the second stimulus.
