Turbo Tax gave me a estimated refund date that has passed

I filed my taxes on February 2 and they were excepted on February 12. TurboTax gave me an estimated refund date of March 5. I still have not received my taxes. There are no status bar’s when I check my status return on the IRS website. Is this happening to anyone else? I also have not received any letters in the mail asking for identity confirmation. This has never happened to me before.
