I have one payout that has been in review for 20 days and another that's been in review for 7 days. I'm starting to fear that I'll never get paid. People are buying my stuff, I'm just not getting paid for it.

Please post your payout ID in the payout support topic pinned at the top of this category. But if you look at posts by other people, three-week waiting times aren't unusual as of late.
