This is awful; it's a way for TurboTax to collect more information about people. They need an address and banking information and conveniently they mention for-profit services to "help" with this.
The actual IRS and Treasury Dept are working to make as many of these informational returns as unnecessary as possible, and actual homeless services in various cities are going to be able to pick up where that leaves off, giving homeless people the FULL amount of their stimulus check.
