Some doubts about filing an Income Tax Return from Wundertax

Hello,

I have some doubts while filing the Income Tax Return from Wundertax, what should be filled in this [section](https://ibb.co/GMyxpx9) and [this](https://ibb.co/hdNt0ZR) ? We live in Munich and my wife’s office is in Berlin, she works remotely full-time. The information I fill in this changes the expected tax return to the amount of 1000s of Euros.
Question:
1. I see that the information regarding the distance to the office is for commuter allowance, but is a mandatory field. As a remote worker is this relevant for her?
2. How can I claim the corona lump sum amount that is based on the number of days worked from home? if the number of Work from home days is less than 140 here, the tax return is €1500, if the number of work from home days is more than 140, the tax return is -€80 (negative).
