where do I add my wife's W2?

When you are entering income on a joint return, every income entry screen will either have a spot with both spouse’s names there, or when you click to enter a W-2, 1099R, etc. it will ask you by name which spouse it is for.  You do not have to wait for the software to “ask” you for your spouse’s income.

 

Go to Federal>Wages and Income and click Add W-2

You enter W-2 forms in the Wages and Income section, then Wages and Salaries, then Form W-2:

 

TurboTax should ask if you have another W-2 to enter. I'm assuming you are "Married filing jointly", so when you say yes, it will ask you if this W-2 is for you or your wife. Then it will ask if you want to import the W-2 from a payroll service or enter the data yourself. Pick one and proceed. 

If TurboTax Online did not ask for the spouse's W-2, have you elected the married filing jointly filing status?

 

• Select My Info down the left side of the screen.
• At the screen About your household, verify that you are Married and that you Plan to file jointly.

 

Enter the spouse's W-2 by following these steps:

 

• Down the left side of the screen, click on Federal.
• Down the left side of the screen, click on Wages & Income.
• Click to the right of Job (W-2).
• Select Add a new W-2.
