Funds remain pending for 5 days. So you will have to wait for 5 days after the payment was released by the client.
If you go to the reports page, you should see a question mark icon next to the text "Pending ?". If you hover or click on the question mark you should find a clear explanation(I have attached it).
On that reports page also, you should be able to see the date for the funds to be available which should available by 18th May 2021 according to my calculations.
Hope that answers the question.
Ghazali is right. When your client releases a milestone or final payment on a fixed-price job, it immediately shows as pending on your financial account. Pending payments become available for you to withdraw after the standard five-day security period. Please check this help article for more information.
