I think the mods are going to close the thread because I think this kind of thing doesn't go here, but I want to answer you first.
One of the things you have to understand is that an archetype that has an advantage over another archetype wins. It's like if you want a fire type pokemon to beat you 1 vs 1 against water type pokemon, it's hard.
Although, there are ways for fire type pokemon to win, either because you have a super effective move against water type or you have a certain strategy that advantage you. Well, exactly the same thing happens in the MUs of Tailwind Offense vs TR. TR has an advantage against TW, but it is not impossible for it to win, but you have to plan changes in your team to have answers to TR, for example by putting a P2 or Amoonguss on the team, although there are a thousand ways to check TR with Tailwind Offense.
Here are some replays of very good DOU players who win with TW Off to TR in tours, so you can get some ideas from them.

SCL Z strats vs Actuarily

Some replays are a bit old and the teams with TR are SemisTRs because I have been in a hurry to be able to send the message before they close the thread, but I think you can get an idea, and I encourage you to look for your own matches from the last DOU tours so that you can keep learning.
I hope I helped you and forgive my English, I'm not too good.
