I still have not received my taxes from last years return

If you're asking about a tax refund that you believe you're due, you can check the status here.

However, since it's been nearly a year are you certain that you actually filed your tax return? You can check weather you're tax return was accepted by the IRS here: https://turbotax.intuit.com/after-you-file/ 

How will I know that the IRS has received my tax return?

Ever worry that your return might get lost in the mail? E-filing lets you rest easy. When you send a return by mail, you have no way of knowing if the IRS received your return unless you pay extra for certified mail with a return receipt. It could take weeks for you to get that receipt.

But if you file electronically, the IRS notifies you by email within 48 hours that it has received your return. And if the IRS detects any errors, it will send an error code that TurboTax will translate into a text message telling you what the problem is, how to fix it, and how to retransmit your return.
