Log into your Online account. At the Tax Home what is showing for the "Return Status" for your Federal return and state return (if applicable)?
If you efiled, you can also check the efile status with this tool. What does it show? Does it show pending, accepted, rejected, or no record found?

If you efiled, you should have received an email after filing saying that the return had been submitted. It should be followed by a second email in 24-48 hours (sometimes sooner, sometimes later) saying whether the return was accepted or rejected.
