I'm nervous about entering in deductible school expenses. I don't want to mess up!

This answer might help you with that.

Some rules, on what school expenses you can deduct, depends on which credit you are eligible for.

Enter all the expenses you incurred because of school and the Turbotax Software will know if it needs to exclude any.
