You cannot file your tax return until you have received all of your W-2s, 1099s, and other tax documents. Your employers have until February 1 to send you your W-2s. All of your W-2s and 1099s must be entered on a single tax return.
The IRS will start accepting 2022 tax returns sometime in late January. They have not yet announced the exact date. TurboTax will let you "e-file" in early January, but your tax return will not really be filed. TurboTax will just hold it until the IRS begins accepting returns. Nothing will be done with it before then. If you submit it early, be aware that 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.
