How to file UBER INCOME T2125? HELP PLEASE

Hello everyone! I have a client who drove for UBER for two months and stopped and not looking to do it again.

Here's what I have:

* Tax Summary 2020 from UBER*

Gross Uber Ride Fare - $842.55CAD

Booking Fee - $189.75

Tips - $95.42

GST on UBER rides - $52.84

"OTHER POTENTIAL DEDUCTION"

On Trip Mileage - 460KM

*January 2020 Gas Receipts*

Total = $368.94

*February 2020 Gas Receipts

Total = $340.54

*Dash Cam Receipt*

On filling out T2125

PART 3A

Gross Income - $1180.56

Minus GST - $52.84

Adjusted Gross Sales - $1127.72

PART 4 - NET INCOME BEFORE ADJUSTMENTS

Management and Admin Fees - $189.75 - This is where I entered the Booking Fees

Questions : 

1. Where do I enter the Fuel Cost? - I think it goes to the Vehicle Expenses but Im not sure If I should be entering/claiming the full amount as it seems absurd when compared to the about he drove for UBER which is only 460KM in total. 

2. Should I be claiming CCA or not? 

3. Does anybody have a sample guideline for UBER Income T2125 Filing. I found one from TurboTax, but I am looking for an article that has a sample that I can follow?

4. Im not sure how to fill this one out.. Please see attached picture and labeled "4"

Thanks in advance you guys!
