No.  No one can look up your W-2's for you.  Your employers have until January 31 to issue your W-2's.  Some--but not all--employers partner with TurboTax to make your W-2 available to import in to your tax return.  You still need some of the information from the W-2 to import it--like the amount in Box 1.  You just have to wait until you have all of your W-2's.

ALL of your W-2's must be entered on the SAME tax return.  The employers who issue them also report them to the IRS with your Social Security number on them, so what you enter on your tax return must match what was reported by the employers.

 There really should be no rush to file--the IRS will not be accepting/rejecting returns until January 28.  Many tax documents such as W-2's, 1099's, 1098's, etc. have not been mailed out yet. You may not have everything you need until mid-February.  If you file too early and then find out another important document just arrived in your mailbox, you have to go through the agony of amending your return--which takes about 4 months.
