With more than 40 million taxpayers yet to file, it's likely a portion of those returns will end up flagged for review — leaving those taxpayers with an unknown wait for their refunds, rather than the usual three-week turnaround. "My tax person said he was shocked if I wouldn't see my refund in 10 days, and it's been over two months," said Hillary Osborne, 41. She filed her 2020 tax return on February 27. So far, nothing. "I check 'Where's My Refund?,' and it says it's still being processed — I called the IRS after 21 days, and you can't get through to anyone." Osborne, a single mother who works as a project administrator in Tennessee, said her refund should amount to more than $4,400, which will cover about four months of rent. She said her taxes are fairly simple, but she wondered if something about the stimulus checks have tied up her return.
