I would suggest that you have a look at What should I wipe in TWRP? from the official TWRP site.Should I format data if upgrading from latest stable? Thank you.
Mi 9t.
"If you are switching ROMs (changing from one ROM to a completely different one) then you should perform a factory reset."
Read on - you will see what the Factory reset does, and what you don't need to do!
It also says, ".... Depending on your device and its configuration, you may have options for wiping internal storage, external storage, sd-ext, android_secure, and/or an option for formatting data. There's almost no reason that you would ever need to use these items."
etc. etc. etc.
