I still haven't received my tax return yet its been 7 weeks now

If you efiled, double-check to be sure the return was efiled successfully and accepted.
If you used Online TurboTax, you can sign into your Online Account and check the efile status at the Tax Home.  If you used desktop software, you can check from within the software.

If that showed it was accepted, (or if you mailed a paper return), you can use the "Where's My Refund" tool at the IRS website below to monitor the status of your Federal refund.

What info is displayed there about your refund?
