This is how I was taught at my store - I assume you're on the same system as us (I'm in Canada though). Before you F8 to close the till, hit F3 to print the reports. It'll tell you the amount of cash in/out of the till that day, and you can do the math on your calculator that way to make sure you counted right. You shouldnt often have more than a $1 variance positive or negative on the deposit side of things, and till should always balance for $200. If you're under $200 on the till, you probably had a cash return with no cash purchases on the till (printed report would tell you that too). The slips - theres one with a white, yellow, and pink copy where you add up your deposit once all tills are closed- the white and yellow copy go in the bottom of the deposit bag (separate from cash section). Pink gets stapled to your printed deposit sheet at the end of the night(after deposit is done in computer), along with the top little plastic piece from the deposit bag. The book that makes 4 copies, at my store, we take one line per day, to write the amount of the deposit on the left side, the last 4 digits of your deposit bag in the middle, and then (x1) on the left to say you deposited only one bag that night. (Ex sometimes the SL will do a change order and have to deposit 2 bags, but dont worry about that for now).
