You received an e-mail from the IRS

Actually you didn’t. There are some internet scams that use e-mails, supposedly from the IRS, in an attempt to get identity information for illegal purposes. These e-mails may tell you about a refund due you, or that something is wrong with your tax account. They may have links that direct you to the real IRS website, and then re-direct you to a bogus website that has been set up. The IRS does not initiate communications with taxpayers through e-mail. Communication from the IRS is initiated through mailed correspondence.

If you receive an e-mail supposedly from the IRS, or directing you to an IRS site, the IRS advises:

Do not reply,
Do not open any attachments; they may infect your computer,
Forward the e-mail to the IRS at phishing@irs.gov
After forwarding the message, delete the e-mail.
