TSH is a hormone in the brain that stimulates the thyroid to make thyroid hormone, hence it's called thyroid-stimulating hormone. TSH is usually low when the thyroid hormone is high (less TSH is needed) . Now level up. TRH (thyroid releasing hormone ) stimulates TSH, when TRH is low (this is rare) then the whole chain is low; e.g. low TSH, and thyroid hormones is low. So more details are needed

All laboratory results need to be interpreted in the clinical context and the doctor who ordered the tests is usually in the best position to do that. Talk to the doctor who ordered the tests. Having said that, your TSH level in the normal range. It is not an indication of underactive thyroid. It may be at the borderline for hyperactive thyroid. Wish you good health!
