    Settings for BIAB are also in https://www.brewersfriend.com/homebrew/profile/equipment. Though for first batch it's hard to know if you'd change them from the default. The main one would be the boil off rate. You've done a test boil for 15 minutes or so to show that you'll boil off 1.5 gallons an hour? I'd also change the default grain absorption rate for BIAB. If you end up squeezing the bag it's half the default amount. Once you've updated them you can use the quick water requirements to update your mash amount and boil size.

    For a first batch I'd use the recipe tools to scale the efficiency to 60%. It's so much easier to just add some previously boiled water to the kettle at the end of the boil if you do hit 70% rather than stuffing around with adding DME or just ending up brewing a session beer. Once you've got the numbers from your you can adjust it up.
