Please note that the correct spelling of the last word in your sentence above is debt.
You state that the amount of $1M you received was from/resulted from/arose from your alleged redemption of units in the XYZ unit trust which was then used to pay off your debt.
I don't like "was from" at all. resulted from and arose from are acceptable but I prefer proceeded from, which is used to refer to the source of funds. "result from" would be more usual for calculations, for example:
- The amount of $1M resulted from adding up $0.4M and $0.6M.
As regards "arise from," this verb is more usual to refer to situations or facts derived from others ("result from" can also be used with this meaning), and an amount of money is not a situation or a fact.
