You cannot claim your spouse as a dependent on your tax return. If you are still married, you choices are:
- married filing jointly; or
- married filling separately.
If you were still legally married as of December 31, 2020 and a child lives with you, you can qualify for Head of Household under a slightly different set of rules. Please this article: Can a married person claim Head of Household filing status?
Does your spouse owe child support to someone else? If so, you can protect your refund by either filing separately or, if you're filing jointly, filing a request for Injured Spouse status. Please see this TurboTax Help article for more information: How do I file Form 8379, Injured Spouse Allocation...
