I'm afraid I don't know whether or not stopping HC is likely to affect your TSH. FT4 is close to top of range so I wouldn't increase dose but I would retest in 6 weeks to see what's happening.
VitD 57 is suboptimal. Replete is 75-200 and most members are comfortable around 100. Supplement 5,000iu daily for 6-8 weeks and then reduce to 5,000iu alternate days. Take vitamin D 4 hours away from Levothyroxine.

I can't find any literature that corresponds with these bloods so I can only assume stopping HC abruptly has had some effect on the HPA axis and TSH , I shall follow your advice and retest at the end of the month
I certainly don't feel like my TSH is that high so must assume it's artificially elevated due to some adjustments in my body
