You can contact customer support in the morning as far as your TurboTax account is concerned. There is a procedure where you can take over ownership of an account by providing proof of your identity. This is usually used when someone forgets their password, or changes their email address or their cell phone number used for verification and forgets to update their account. I don’t know if it would be available to you in the case of a marital dispute.
You can also get transcripts of your tax returns from the IRS. You need to register at the IRS for an individual online account with your own unique username and password. However, you should then have access to any joint return that was filed that included your Social Security number. You can get transcripts online for the past three years I think, and you can get transcripts or copies of all the returns by filing a paper form with the IRS.

This won’t get you any money, but it will tell you what has been going on.
