Hey there,
Here are a few steps you help you request your money:
- Complete the tax interview (You mentioned you’ve done it already, but I’m including it for completeness)
- Add some payment info on your profile (Like Paypal, or any other service you are using)
- Wait ~7 days from when the donation was made
- After all this you should now be able to request the money from your dashboard.
Hope this helps. Sometimes there might be some review pending, especially for new creators, so things might take an extra few days.
