Your employer was required to have your W-2 at least on its way to you by January 31st. If you did not receive it, I would contact them for a duplicate W-2, or ask if they are holding it for you for some reason, such as if it was sent back to them as undeliverable.
I would verify that your mailing address on file with them is correct so that you receive mailings from them in the future.
You can import W-2 information into TurboTax, but it requires information from the W-2, such as the value in Box 1 and the Control Number in Box D.
