I have a tub of TNC Trace Mix I found in my shed, which I am going to use in my fert mix, but I'm not sure which chelator is used, as I have very hard water I think I need dtpa? does anybody know or where can I find out the info.

What iron chelator is in TNC Trace Mix?

You might have to try to contact the company for that info.
Fwiw, their Complete Aquarium Plant Food lists EDTA.
Their Iron AT lists DPTA which is good for pH in the low 7s but by the time pH gets to 8 about 80% of the iron will be precipitated out.
The strongest chelator is EDHAA which keeps iron available up to pH 9 or more.
They don’t list a trace mix on their site so perhaps they no longer offer it.

They don't do it any more, It was bought more than ten years ago if i remember, it's when you could get all the different salts from them.

Things always change, don’t they?

Mostly for the worse.
As far as I recall, it contains EDTA chelation but no DTPA. Is there any label or additional information on the tub?

No, just lists the ingredients and iron is just shown as fe, doesn't say what chelator
Can you take a picture?

I am working away at the minute but will be back Friday/Saturday so will get one then.

As mentioned earlier, and as @Hanuman pointed out, it is EDTA-based. Most companies generally use EDTA, while some combine both EDTA and DTPA, especially for Iron.
I highly recommend considering Solufeed Coir TEC. You can also combine both, using 0.05 ppm Fe from TNC and 0.05 ppm Fe from Solufeed Coir TEC.

Sounds good, so I presume I mix the 2 50/50 and mix in water to dose as per TNC instructions?
What is the size of your aquarium? Will you be using a 500 ml container to mix and store the solution? What is your preferred dosage, such as 10 ml, 20 ml, etc.?

Dosage doesn't matter as I have dosers but as a rule I try to dose 50ml (It's my ocd causing me to have a round figure)
680 litre and 400 litre.
