how to use coinreporting.com to do taxes

I just have a simple question about using coinreporting.com, creating accounts and importing data.
I'm a little unclear on the correct sequence of steps to submit my trades from an exchange.
Coinreporting.com has a "Learning Center" with an faq and so on. For entering data from a bank account or crypto exchange or whatever, you have to create an account. Coinreporting's learning center says go to
accounts > add new account > digital exchange
type in a name, and click add account. There is a separate importing function, and how to import trade data into the account after I create it is unclear.
I have three accounts at Bitfinex. Say I go to the accounts tab and create three accounts named BFX1, BFX2 and BFX3.
I will have to import csv files from Bitfinex for three different accounts. How do I assign each csv file to the correct account created in the first step? Or do I download first, then create the accounts? I would appreciate some gentle ELI5 from someone a little more familiar with this stuff who has used coinreporting.com. I'm inexperienced and need to get started with baby steps.
