This is my first time doing my taxes are a married man. My wife already filed her taxes as jointly. Should I do the same?

No, when a couple files Married Filing Jointly, only one tax return is filed to report all of the couple's income and deductions.  If your wife filed a return already, you should be sure that she included your income and her income as part of the return.  

If she used the Married Filing Separately filing status, then you need to file a Married Filing Separately return as well.  

Also, be aware, that returns filed electronically do not have a physical signature like a paper return, but each spouse is required to sign a joint tax return because you are both responsible for what it is reporting.

Sounds like you are a couple of confused newlyweds who did not understand how to file a joint tax return.  When are legally married, your filing choices are to file married filing jointly or married filing separately.   Jointly is almost always better.    When you file a joint return your prepare ONE tax return and it has all the information from both spouses on that one Form 1040----both names, income information from both of you, all of your combined credits, deductions, dependents (if any)----all on ONE tax return.   

If your wife already filed a tax return and says it was a "joint" return----you need to find out if your income was included on that return.  Did she include your W-2 or your 1099 income?   If it was not on there, then after the IRS processes that incorrect return, it will have to be amended and your income has to be added to it.  

You need to see what was filed----look at a printed copy of it and see if the filing status up near the top of the Form 1040 shows that you are filing as Married Filing Jointly.   Then check to see if your income was included.
