If anyone is looking for a good tutorial/user guide for flying MSFS 2020, and doesn't want to spend the earth, I can highly recommend A Guide to Flight Simulator - Extended Edition from SoFly.
It can be bought and downloaded in PDF format from https://sofly.io/a-guide-to-flight-simulator-extended-edition/ or the FlightSim store https://store.flightsim.com/
I bought my copy from Flightsim store for about NZD$40 in August 2021. At the moment, updates are free (of which they release every Sim Update).
Latest update is about 430 pages long, in full colour.
There are tutorials on G1000, IFR, Airbus Neo, Daher TBM 930, Icon A5 (tutorial is actually set in NZ), Top Rudder Solo 103, PMDG DC6 and the Junkers JU52. Plus, how to get the most out of the World Map.
Stacks of information on a lot of airports, and summaries of all aircraft.
There is also Change Logs for every sim and world update.
On PC, the guide can be integrated into MSFS itself.
The publishers are very receptive to feedback, and I have provided plenty of typo fixes to them, which they have fixed promptly for the next release.
