We get a weekly settlement sheet with total income we got along with deductions. Where do we input the income and the deductions ?

You need to create some items first. A service item that is linked to an income account, and non inventory items that are linked to the expense account you use for those expenses.

Then you do a sales receipt for that customer/organization
line one: use the service item and enter the full amount
lines two and the rest: use the non inventory items for the expenses listed, use a qty of negative one for each expense.
save and then deposit
