If you're sure the return was accepted, and everything's being entered correctly at the IRS WMR tool, using my recommendations above, there aren't any additional tricks. All you can do is keep checking the IRS WMR occasionally.
If you efiled, and after 21 days from acceptance, if you're still not seeing any info there, you can phone the IRS and speak to an agent. It's too early to contact them now. In the first 21 days, they say they can't research the status of your refund and tell you anything different.
In the meantime, if you wish, you could try phoning the IRS refund hotline and see if it can look you up over the phone in their automated system, but you may get the same result. Listen to all of the recorded message, then it will allow you to check the automated system. 800-829-1954
