Yes: Hypothyroidism can cause macrocytic anemia. This anemia is due to poor nutrition and/or poor absorption of folate and B12. Thyroid hormones assist in that absorption, so low levels of T3 (liothyronine) and T4 can lead to that anemia. Treatment should not only address the anemia, but also the hypothyroidism.

Macrocytic anemia: Yes, hypothyroidism can cause macrocytic anemia. The thyroid hormones are involved in B12 and Folic Acid absorption. Examine your diet, cut out the junk food, supplement B vits/B12 in particular. However, 8.5 is lower than I would expect. Look for GI bleeding source, consider a colonoscopy.
