TPO antibodies may be under the limit but a bit on the high side. I'm not Hashi's and have had quite a few antibody tests over the years, always come back low, never more than 12 for either TPO or TG. With yours being 20, I would retest at some point as one negative doesn't rule out Hashi's.
Vit D is way too low, needs to be 100-150nmol according to the Vit D Council.
