If you are filing married filing separately and you live together, you should be able to work this out.
If you are separated, and going to file as married filing separately, it is up to you to provide accurate information. Try to work it out with your spouse or your spouse's attorney. However, if you do your due diligence, and are unable to confirm the facts, the IRS will address any conflicts.
Due to taxpayer privacy laws, no one -- not Turbotax and not even the IRS -- can share with you what someone else put in their tax return.
