You do not need a W-4----you need your W-2 from the employer.
W-2's come from employers. There is not a federal or national website that provides W-2’s.
You might need to phone, drop in, email and/or snail mail an old employer to make sure they know where to send your W-2.

Other ways to get W-2’s:
You can get a wage and income transcript from the IRS: It will not show the actual W-2, 1099’s, etc, but will show the income information the IRS received. It will not, however, show your state information. It will only show the federal information.
