why can't I just file ...what's the hold up?

Where are you stuck?

ALL of your W-2’s must be entered on the SAME tax return.  

Go to Federal>Wages & Income to enter a W-2.

After you enter the first one, you click Add Another W-2.

W-2's come from your employer, and they have until January 31 to issue it.  Some employers allow you to import the W-2 through the software, but for security reasons you still need information from the actual W-2 to import it. Some employers have payroll sites that will have your W-2. 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.
