“I'd like to cash this. Do I need to fill out a deposit slip or anything?”

You have a paycheck from your part-time job. You'd like to get cash instead of putting the money into your bank account. You go to a bank and ask the teller:

I'd like to cash this. Do I need to fill out a deposit slip or anything?

I'd like to (do something)

Use this phrase to ask for services at stores, banks, and so on:

Hi. I'd like to deposit this into checking, please.

I'd like to send this via registered mail.

I'd like to cancel my membership.

cash (a check)

"Cashing" a check means giving it to a bank, and getting the cash value of the check from them. You can "cash" a paycheck, a personal check, a tax-return check, etc.

fill out (a form)

You "fill out" forms like applications, information sheets, contracts, and so on. "Filling out" a form means writing answers into the blank lines and boxes printed on it. For example, you "fill out" tax forms when you're preparing your taxes for the year:

If you make less than a hundred thousand dollars, you should fill out form 1040-EZ.

a deposit slip

A "slip" is like a form, but it's usually smaller than a full sheet of paper. Some examples of "slips" are:

• permissions slips (for school field trips, etc.)
• deposit slips
• wire transfer slips
• a pink slip (which is a piece of paper telling someone that they've been fired or laid off)

"Deposit slips" are pieces of paper that you have to fill out when you're depositing money into a bank account. You write your name, the amount of money you're depositing, your account number, and so on.
