If you submit your tax return before IRS e-filing opens, your tax return will not really be filed. As you said, it will just sit in a queue at TurboTax, not at the IRS. There is no advantage to having your tax return held in the TurboTax queue. You will not get your refund any faster. But once you submit it you can't cancel it or get it back to make changes or corrections if you find that you made an error or left something out. Are you really sure that you have nothing to report besides your W-2?
