When you file as Married Filing Joint, your spouse is not a dependent. You enter both of your & your spouses information but you do not choose a spouse as a dependent.
If that is what you did, you need to go back & remove you as a dependent.
It's not important whose name goes first on a joint return— at least not to the government — but what does matter is being consistent with each subsequent return you file. Changing the established name order isn't the end of the world, but it could result in processing delays for your taxes.
You can't change who's name is first on an account you have been filing as Joint in the program. You would have to change each information under each name & that can get confusing & a pain.
