My GF has yet to get hers or her tax return. The stimulus check went to an address from 2 years ago and she would be on hold for hours just trying to get her address updated and stopped calling. There's maybe $3k just sitting out there but the Treasury can't get it to her. This is why I vote blue, we need to adequately fund our government systems or face issues like this.
a lot of people also ended up having to get checks even though they filed last year and everything. If you used any of the "pay for your e-filing with your tax refund", "get your tax refund as an amazon gift card with a 5% bonus!" etc type arrangements, your tax filing company actually was the bank account of record and the IRS has to send you a check since they don't have real banking info for you.
