You do not need to submit your receipts to the IRS through TurboTax.
The IRS does not require these receipts generally unless your figures represent something unusual to the general public or expenses. For education, $3,800 is not a difficult amount to spend. Many required books, computer equipment and other expenditures are customary and usual.
However with education expenses and other entries that require you to submit figures, you should be able to substantiate what you enter to the IRS if they ask you to. These records can be from personal records, bank or credit card statements, mileage logs, etc.
