@jcamp_331 If you are filing a joint return you qualify for 2800. Your AGI is under max. Did you get any of the 3rd Stimulus payment last year? You need to enter the full amount you got. You should each get IRS letter 6475 for half. But you need to enter the total for both. So Double check your bank account and your IRS account (both accounts if married).

1040 Line 30 is only if you didn't get the full amount or qualify for more.
It is not taxable and you aren't paying it back. Your 2021 return starts out by assuming you didn't get any Stimulus payments so it gives you credit for the full amount and your refund was too high. Then near the end you enter how much you actually got so it only gives you the difference if any. So you don't get it again.
