Call the IRS at 800-829-1040,and explain your situation, you are not the first person to have this trouble.
If this is a current year return, you can file your return by mail as married filed separate or head of household (if you have kids). Your refund will be slow, but the IRS will be after your hubby for filing a return without your approval.
You can get prior year returns (2015 and earlier) from the IRS, for a fee. The will explain the procedure for you.
Good Luck
