How do I get a federal tax refund? I double paid by mistake.

Is there a form I need to complete, and if so what is the form and where to I get it, complete it, and mail it?

Is your tax return correct? If your return shows the correct amount of tax and you paid more than that, the best thing to do is just call the IRS and tell them about the mistake so they can refund your overpayment. Otherwise, they'll likely apply the excess to your next year's taxes. The phone number for questions about individual returns is 800-829-1040.
