How come I didn’t get a stimulus

[Anonymous]

could be one of many reasons.  however, when you file your 2020 return, you'll be able to claim it if you qualify.

First, it depends on your filing status: if you’re single, the payment is $1,200, but it doubles for a married couple filing jointly to $2,400. It also depends on your family size; you’ll get an additional $500 for every child under the age of 17. If you are claimed as a dependent on someone else’s tax return, you are not entitled to any payment at all.
For high-income taxpayers, it depends on just how high your income goes; a married couple will start to lose the payment once adjusted gross income (AGI) exceeds $150,000, and the same will occur for a single taxpayer once AGI exceeds $75,000.
Your payment also depends on whether or not you file your tax return.

if the IRS sent you a payment but it got lost or someone else cashed it, you will have issues that will need to be resolved when the IRS sends you a notice denying the credit.
