Where or how do I enter cash wages with no W2 in Turbo Tax Deluxe?

If your employer did not withhold taxes you have to enter your earnings as self-employment income on Schedule C.  You can deduct any expenses you had against the earnings. You will be considered a business, but you do not have to have a business name.  You can use your own name. To enter self employment income: 

1. Open (continue) your return, if you don't already have it open.
2. Inside TurboTax, search for schedule c and click or tap the "Jump to" link in the search results.
3. Answer Yes to Did you have any self-employment income or expenses? or Did you have any income and expenses for a business in 2017? and follow the onscreen instructions.

 If your employer withheld taxes from your cash wages, they are required to give you a W-2.  You will need that information to file. 

I am not self-employed but have income from 2019 that was not put on my W-2. So do I put the work description of my actual job? And what do I put as my address?

If you did not receive a 1099-MISC:

• Under the Federal menu, click on Wages & Income
• Expand the menu for Less Common Income
• Click Start/Revisit next to Miscellaneous Income, 1099-A, 1099-C
• Click Start/Revisit next to the first option, Other income not already reported on a Form W-2 or Form 1099
• Answer Yes to the question, Did you receive other wages?
• Continue through the screens until you get to Any Other Earned Income
• Answer Yes to the question, Did you earn any other wages?
• On the next screen, choose Employee compensation that was not reported on a W-2
• Enter the information on the screens that follow

You should not need to include an address on this information.
