How long have you been on this protocol and how do you feel overall?
Need a more thorough set of labs as you are missing the most critical blood marker free testosterone.
TT is important to know but FT is what truly matters as its the active unbound fraction of T responsible for the positive effects.
In order to know where your FT truly sits you would need to have it tested using the most accurate assay the gold standard Equilibrium Dialysis especially in cases of altered SHBG (low/high).
If you do not have access to such which is most likely the case seeing as you liven the UK then you will need to use/rely on the next best testing method the go to linear law-of-mass action Vermeulen (cFTV) which will give a good approximation.
Also missing critical blood markers RBCs, hemoglobin, hematocrit and iron/ferritin.
Need a full thyroid panel too.
As you can see on a daily injection protocol 20 mg T (140 mg/week) you are hitting a robust TT 674.9 ng/dL (23.4 nmol/L) but it means nothing when looking at the bigger picture here without knowing where the most critical fraction FT sits.
We can easily calculate your FT using the cFTV seeing as you had your SHBG tested.
The calculator is available online for free to the general public.
With a robust TT 674.9 nmol/L, lowish SHBG 16 nmol/L and Albumin 4.3 g/dL (default) your high-end cFTV 20.7 ng/dL would be a healthy.

Even though your TT is far from high with a lowish SHBG 16 nmol/L your FT is still high-end.
Men with low or lowish SHBG do not need to hit a high TT in order to achieve a healthy/high FT.
Would not get too caught up on your high estradiol if you feel well overall.
If you have elevated CRP or you were one of those poor bastards who crushed their estradiol from overusing an aromatase inhibitor (AI) then you’d want the most accurate assay available LC-MS/MS, or better yet a CDC-standardized LC-MS/MS assay (US).
Otherwise the standard immunoassay is usually sufficient.
Your prolactin is just over the upper limit but I would not be too concerned unless you were experiencing sides.
