**Tax Year 2017**Separated May; divorce final Dec. 20. Full-time college son and living at home 24-yr. old daughter. How do I separate joint assets and support of kids for half year?

I have no idea what to do. Have had complicated married taxes, with income property and the like, none of which exists anymore. Previous accountant charged $1000 to prep and that is way too much, IMHO. Ex is retired and on MediCare now, and I work only parttime; was on unemployment first half of year. 24-year-old parttime employed daughter lives with me. 22-year-old fulltime student son supported in college jointly but by me when not in school. He worked parttime earlier in the year and did make over $5000, I believe. Me and two kids covered by ACA right now, so our combined income is low.
Can I use TurboTax in this new situation, or do I still need the ripoff accountant?
