Touch Typing

I am trying to use current social isolation time to learn to touch type. I have been typing using 4 fingers at best for the last 15 years, so I have lots of bad habits. Unfortunately, my home office mode requires me to write a lot. I cannot simply stop everything and focus on slowly getting proficient with touch typing.

Do you have any hints on how to learn touch typing while having to produce large quantities of written content? At the moment I can invest about 1h a day for practicing.
