Checking IRS Tax Refund status

Hello, I filed my tax on 2/16 and was waiting for the tax return. When I check the IRS check refund status, it's indicating, "We cannot provide any information about your refund. You must wait at least 24 hours after you get the acknowledgement e-mail that your tax return was received by the IRS" I got the confirmation on Turbotax that Federal and CA accepted my tax return on the same day. Is this something I have to worry about? Please advise!
