What if I dont have a check stub for a job ?

No, IRS regulations prevent you from e-filing a return that has a Form 4852, Substitute W-2.  

You can file a conventional paper return that includes IRS Form 4852 if all efforts to obtain a W-2 from your employer have failed. Here's how to fill one out:

1. In your TurboTax program, search for W-2 and then select the Jump to link in the search results to get to the W-2 entry screen.
2. Fill out your W-2 as best you can using the information from your last paystub.
3. When finished, proceed through the interview. Eventually you'll get to the Do any of these uncommon situations apply to this W-2? screen.
   • Check the Substitute form box near the bottom.
   • Check any other box(es) that apply to your W-2 before selecting Continue.
4. Eventually you'll come to a screen which will ask if you want to complete Form 4852 for wages paid. Answer Yes and carefully follow the onscreen instructions.

Returns including Form 4852 can't be e-filed per IRS regulations.
