Unfortunately being an Endocrinologist does not guarantee a doctor that will treat clinically, as described above. Many of them specialize in diabetes not thyroid. Also, many of them have the "Immaculate TSH Belief and only pay attention to that. Wrong. If they test beyond TSH, then they use "Reference Range Endocrinology", by which they will tell you that a thyroid test that falls anywhere within the range is adequate. That is also wrong, as discussed in the paper linked above.
I suggest that you try to get the current doctor to read the paper and consent to treating clinically, as described. If that doesn't work, you will need to find a doctor that will treat clinically. If you will tell us your location, perhaps we can give you the name of a doctor that has been recommended by other thyroid patients in your area.
Sorry for the typing errors in the first reply. Corrected in the following.
Your daughter definitely has a thyroid problem. TSH is a pituitary hormone that is affected by so many things that at best it is only an indicator, to be considered along with more important indicators such as symptoms and also levels of the biologically active thyroid hormones Free T4 and Free T3. She has many symptoms of hypothyroidism plus her Free T4 was way too low in the range and, assuming that her Free T3 will be consistent with her Total T3, that would also too low.
A good thyroid doctor will treat a hypothyroid patient clinically by testing and adjusting Free T4 and Free T3 levels as needed to relieve symptoms, without being constrained by resultant TSH levels. Symptom relief should be all important, not just test results. You can confirm all this by reading at least the first two pages of the following link, and more if you want to get into the discussion and scientific evidence of all that is recommended.

The doctors are overlooking your daughter's hypothyroidism because they pay too much attention to TSH. Your daughter's TSH is in range because she doesn't have primary hypothyroidism, but central hypothyroidism. With central there is a dysfunction in the hypothalamus/pituitary system that results in TSH levels too low to adequately simulate the thyroid gland to produce hormone.
Your daughter needs to be started on thyroid medication and then gradually increase the dosage as needed to relieve symptoms. Many of us have found that we needed Free T4 at the middle of the range, at minimum, and Free T3 in the upper half of the range, and adjusted as required to relieve symptoms. In addition hypothyroid patients are frequently too low in the ranges for Vitamin D, B12 and ferritin. So she should be tested of those and then supplement as needed to optimize. D should be at least 50, B12 in the upper end of its range and ferritin should be at least 70.
If her doctor is resistant to any of this, then you should give him a copy of the link and ask that she be treated clinically as described.
