Stimulus for F-2 holder spouse

[sajib056]

I came to the US in 2016 with my wife and we are resident aliens as per SPT from last year. My wife is on F2 visa and she will be applying for ITIN this year. While I am checking the refund by filing jointly from TurboTax, it shows additional $3618 and $1400 as refunds for my wife. I am confused about what these refunds belong to?

Resident aliens are eligible to receive the third stimulus payment, also known as the plus-up payment. However, you need a valid Social Security number, not an ITIN.

The IRS says:

You aren’t eligible for a payment if any of the following apply:

• You could be claimed as a dependent on another taxpayer’s 2020 tax return
• You’re a nonresident alien.
• You don’t have a valid SSN issued to you by the due date of your tax return (including an extension to October 15 if you request it).
