Yes. The extension applies to everybody. The tuition and fees deduction (TFD) was cancelled at the end of 2017. But, it was recently re-instated for 2018, 2019 and forward. Anybody wanting to claim it for 2018 will have to file an amended 2018 return.
For most people, the extension is meaningless, as the other two education credits are usually better than the TFD.
For more specific advice, you need to say what you are trying to do or what your concern is.
