The IRS is sending more money to some people who didn’t get enough in their original stimulus payments.
The so-called plus-up payments are going to people whose 2020 tax returns show they're owed more money.
Some discrepancies occurred because initial payments were based on 2018 or 2019 returns.
Low-income Social Security recipients and others who didn't file in 2019 or 2020 may still be waiting for money but the IRS is started sending those payments last weekend.
