Please explain.
If you were legally married as of 12/31/23, you must file as married filing jointly, married filing separately, or maybe head of household (if you meet all the qualifications.). You can't file as single.
Furthermore, after the April 15 filing deadline, if you file a joint return, you are not allowed to amend to married filing separately. If you try, it will be disallowed.
If you were not married as all as of 12/31/23 and your joint return was therefore incorrect and not allowed, then you could amend, but the IRS may start asking additional questions. It is not easy to amend from one joint return to two single returns, how are you trying to do this? Do you have turbotax installed on your own computer? Do you have a copy of the original unmodified joint return?
