Why havent i received my refund? I filed 2 months ago

[mesquitebean]

First, you need to be sure the return was successfully filed.  It also depends on how you filed. 

Did you efile, or did you choose to print and mail the return?  If you filed by mail, it can take about 6 weeks, sometimes longer to get a Federal refund.

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.   What does it show there:  accepted, rejected, printed, started, ready to mail, or something else?

If that showed it was accepted, you can use the "Where's My Refund" tool at the IRS website below to monitor the status of your Federal refund.

What is shown there?  Is there any message?

NOTE: When using that tool, use only the Federal refund amount, and not any total refund amount or summary screen that includes a state refund. 
The amount to use is on your Federal Form 1040, Line 35a.
