how do upload a Tyretotravel route to my Android phone?

[magpies]

being an old person and a virgin as fare as this is concerned.

I have both a Garmin 65LM and an android Samsung J5 phone.

I have been sent a route for a TVR runout (S series Barn Farm weekend) which is an itn file. I have just down loaded TYRE onto my Laptop and MyRoute app to my phone.

Question is - how do I transfer the route from my computer to either (or preferably both) phone and Garmin?
