The only thing you can try is to apply for innocent spouse relief. You would either argue that you owed the tax on a joint return because of shenanigans by your spouse that you didn't know about (even though you signed a joint return) OR that even though you both owe the tax, it would be more equitable for it to be paid a different way than the IRS decides to take it.
I don't think the odds are very good with this, and I would wait to apply until after your return is processed and you find out if and how much of your refund is offset for the debt.
