Like a friend completing a lingering Venmo request, the government is gradually settling up with Americans it owes money from the last round of coronavirus stimulus checks.

In a Wednesday news release, the IRS confirmed that it sent out over 1 million supplemental payments to people whose 2020 tax returns qualified them for additional funds this week. These so-called "plus-up" payments total more than $2 billion, meaning the average deposit was roughly $2,000.

The supplemental payments are not a fourth stimulus check. They're actually part of the third set of Economic Impact Payments (EIPs) — the $1,400-per-person ones passed in the American Rescue Plan in March.

In order to quickly distribute these payments, the IRS automatically calculated people's third stimulus checks using data from their 2019 or 2020 taxes (whichever were filed most recently). This allowed the government to deliver EIPs relatively fast, but it also meant that tons of taxpayers were issued payments based on outdated information. If your income level dropped or your family size changed, for example, and the IRS didn't know about it yet, you might not have received the correct amount of aid.
