My understanding is that UHRS sends their info down to clickworker in about 2-3 weeks. You should be able to click on 'My Report' on the UHRS page and see how much money you have (you need to wait for at least 20 mins for the recent stuff to show up). I only started a few days ago so I have quite a bit of money in UHRS that I can't cash out yet because it hasn't been sent to clickworker.
Did you cash out to the wrong PayPal account? First, add that email address to your PayPal account. You can have multiple emails attached. Next, contact support and ask for guidance. If they already sent the payment, it may get stuck in limbo. If they didn't already send it, they may be able to send it to the correct email. It's best to contact support as soon as you can, so that they can advise you on the proper steps for you to get paid.
