it may not matter. Legally separated would only be better if you qualify for head of household - you lived apart from your spouse during the last 6 months of 2024 and paid more than 1/2 the cost of keeping up a home for yourself and dependent child who lived with you for more than 6 months during the year.
if you did not live apart from your spouse for the last 6 months of 2024, then your filing status is either married filing jointly or married filing separately.
