Get your taxes done using TurboTax

Since you were still legally married on 12/31/2024 then you either file your tax return as Married Filing Jointly or Married Filing Separately.

If you have not lived with your spouse at any time during the last 6 months of the year and have a child as a dependent then you could file as Head of Household if you meet the requirements - https://ttlc.intuit.com/turbotax-support/en-us/help-article/taxation/married-person-claim-head-house...
