All fields in blue are required.
In the Setting Name field, type a name for your new setting. Choose a name that reflects the import source for the accounts to which it will be applied, as you will want to be able to easily identify it later. For instance, rather than simply naming it FIFO, use FIFO Fidelity.
For each Security Type, use the drop-down field in the Tax Lot Method column to select the method of your choosing.
