So last year I only had 1 job, but I lost that job. Now I have multiple w-2s from the multiple jobs I have had. How do I do multiple w2s for filing this year?

..or..do you mean that you have extra empty W-2 forms from prior years jobs that transferred into eh 2018 software?

IF so..just enter the one you actually have for 2018, and when you work your way out it with followup questions, there should be a W-2 table listing of the ones you didn't enter ...and you can hit the trashcan symbol by each one and delete the ones no longer needed.

Enter all of the W-2s in your return.  Once you enter the first one, TurboTax will give you the opportunity to enter  additional W-2s.

Please follow these steps:

1. Click on Federal > Wages & Income  
2. Under Wages and Salaries, click the Start/Update box. 
3. On the screen, Let’s get your W-2 info, mark the radio button Work on my W-2 now and click Continue.
   
4. Enter the information from your first W-2.
   
5. Continue through the screens until you come to Here's your W-2 info. 
6. Click the Add another W-2 box and continue to enter another W-2.
7. When you are finished entering all your W-2s, click Done.
