'Die Einzahlung' (the deposit) is the noun form of the separable verb 'einzahlen' (to deposit/pay in; ein + zahlen). It describes the act of depositing money or its result, meaning the money that was deposited.
Das Einzahlen von Bargeld ist am Automaten möglich.
Depositing cash is possible at the ATM.
The phrase 'eine Einzahlung machen' (to make a deposit) is often used. The destination of the money is given with the preposition 'auf' plus the accusative.
Ich muss schnell eine Einzahlung auf mein Sparkonto machen.
I quickly have to make a deposit into my savings account.
You can tell from the verb whether the process or the amount is meant. Phrases like 'eine Einzahlung machen' (to make a deposit) refer to the action. Formulations like 'eine Einzahlung sehen' (to see a deposit) or 'eine Einzahlung beträgt ...' (a deposit amounts to ...) refer to the amount of money.
Die Einzahlung am Schalter dauert nur wenige Minuten.
The deposit at the counter only takes a few minutes.
In formal or business contexts, especially in written language, the phrase 'eine Einzahlung tätigen' (to make/carry out a deposit) is often used instead of 'eine Einzahlung machen' (to make a deposit).
Bitte tätigen Sie die Einzahlung innerhalb von sieben Tagen.
Please make the deposit within seven days.

'die Zahlung' and 'die Einzahlung' can both mean that money is being moved. Use 'Zahlung' when you pay money for something or settle a debt. Use 'Einzahlung' when money goes into an account, for example a bank account, savings account, or customer account. Both words can also refer to the amount of money. The confusion can happen easily because with a deposit, you also hand over money. But the difference is the destination: 'Zahlung' is about paying, while 'Einzahlung' is about putting money into an account.

Nach der Einzahlung am Automaten war das Geld sofort auf meinem Konto.
After the deposit at the ATM, the money was immediately in my account.
