If you are legally married and living together you can only file your tax return as either Married Filing Jointly or Married Filing Separately. You would want to file as Married Filing Jointly for the best tax outcome for you and your spouse.
See this TurboTax support FAQ for filing jointly versus separately - https://ttlc.intuit.com/community/married/help/is-it-better-for-a-married-couple-to-file-jointly-or-...
If for some reason you think you need to file Separately the only information concerning your spouse on your federal tax return is his name and Social Security number. When filing separately you both must use the Standard Deduction or you both must use Itemized Deductions.
What filing status are you using on the tax return?
