Get your taxes done using TurboTax

@alonzhaofamily NO!    You cannot both work on the same joint tax return using the CD/download and different computers.   When you use the CD/download the tax file is only stored on the hard drive of the computer being used to prepare the return.    The two computers would not have a way to share data with each other for the same tax return.     If you want to do things so that you can both work on the same return then use the online software and you can each log on to the online account to work on that return---although you cannot both be logged on at the same time.  

Although----too many cooks spoil the broth.....and two people messing with the same tax return sounds like a recipe for disaster to me ----- right hand needs to know what left hand is doing ---- it would be better for just one of you to enter all of the data for both of you into the software for a joint return.

When you prepare a joint return it is not a "his" and "hers" situation----when you say "I prepared mine...." I am hearing alarm bells.    A joint return is ONE tax return for two people   ---- you will not have "my" return and "his" return.

To begin a new joint return on TurboTax:

You will not be able to merge two previous TT account to start your new joint return.  You can transfer ONE of your 2019 returns into a new return, so choose the most complicated one.  The other spouse’s information needs to be entered manually.

When you enter your own information in My Info, you have to answer the question "Were you married?"  If you click the button for Married, then a drop down will appear that asks, "Do you want to file this return together with your spouse?"  Then you choose yes to file a joint return.  You would then enter your spouse's information into My Info.  Whenever you are entering income information there should then be a spot for you and for your spouse's income information.  Income screens will have spots with each spouse’s name—be careful to enter under the correct names.
