But are you married? When did you get married? If you were married as of Dec 31, 2023 you can only file a joint return or as Married filing Separate. If is too late to amend and change to MFS. A Joint return is one return for the both of you combined. You can amend/change a Joint return to Single for the primary person listed. The other person will have to file a new Single return without using the Joint return. You will need to use the Desktop program to do a 2023 return.
