It's not just based on offset, there is no single answer for your question.

The rim width matters, and so does spoke clearance which is where A, O, R disc or high, med, low disc options become a factor when buying wheels.

TT brakes are beefy in width and can be a tad tricky when fitting wheels. You will be good at your desired 20" sizing which clears the TT rotors height. Now the spoke design from the hub to the wheels inner circumference attachment, is what can be tricky. Add in stepped/reverse lips and it gets narrowed some more but your 20" should not be a problem here. I would say in the +25/30 range but if the offset is higher you will have the option of using spacers to clear the calipers, a good thing.
Hopefully some users with the TT brakes can chime in to help you or have a look around here.

You need the front wheels to be "high Disc" I had 20x9.5 +25 high disc. But offset is up to you
