I had 2 jobs last year and am unclear on how to add both W-2's on my tax prep?

Every 2021 W-2 that you received must be reported on your 2021 tax return, even if they are for small amounts.  Remember that each one of those W-2’s has your Social Security number on it, and that income was reported to the IRS by the employer.  You do not want to get in trouble with the IRS for under-reporting your income.

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.  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.

And….SAVE YOUR OWN W-2!  TURBOTAX DOES NOT SAVE IT FOR YOU.  TurboTax will not have a copy of it in your account and will not have an image even if you snapped a photo.  It is up to you to save it for your own records as stated on the back of the W-2.

If you have already added the first, you should see an entry for it under Job (W-2) in the Federal > Wages and Income section of your return. Select Review next to it. You should come to a screen that says Your W-2 info so far. Underneath your W-2, you will see a button that says Add another W-2, or if you are married there will be two buttons, one for each spouse. Click on the appropriate button and it will take you back to the Let's start with some info from this W-2 screen to determine if TurboTax can import the W-2 automatically. 

If you have not yet added any W-2s to your return, you may get to the appropriate section by selecting Federal on the left menu and Wages and Income along the top of the screen. Click Show more next to Wages and Salaries and then select Start next to Wages and Salaries (W-2). 

Your taxes are determined by your entire income from both jobs. It is common to see your refund rise after entering one and then take a nosedive after entering the second. A lot of calculations are happening behind the scenes to determine the correct taxes, but take the number with a grain of salt until all your income is entered.
