The dates that 2017 filing will open have not been announced yet, but should be announced soon. Last year the IRS started taking returns on January 23, except for a few returns that they pulled early for testing. TurboTax will start allowing efiling before then, but the return will just sit on a server at TurboTax until the IRS starts taking returns. But once you submit it to TurboTax, if you discover an error, an additional W-2, etc., you won't be able to retrieve it to change it. In that case, if the return is accepted by the IRS, you would have to file an amended return later.
You want to be sure you have received all your W-2's, 1099's (if any), etc. before filing. Employers are supposed to furnish you a W-2 by January 31.
