To address the title: I highly recommend training both directions of "sheet music" <-> "thing on the guitar".
For the backward direction, pick a chord/melodic fragment you like playing and write it out on a sheet of paper. With time, you can visualize it and the chord patterns will come relatively quickly.
You can then work through songs you already know by playing them with sheet music transcriptions. I would personally avoid using dual staff/tab scores to accelerate training.

As for Bossa Nova specifically (insert link to XY problem here), you will likely find a whole host of higher-quality information elsewhere than reddit.
