If we e-file our tax return, does TurboTax transmit to the IRS more data than what the IRS would receive if the tax return had just been mailed to them by the taxpayer?

If we e-file our tax return, does TurboTax transmit to the IRS more data than what the IRS would receive if the paper tax return had been mailed to them by the taxpayer?  For example, when calculating our deductible medical expenses using TurboTax, we input details about our total medical expense, such as prescription medicine, travel mileage, insurance premium, etc.  If we e-file our tax return, does the IRS receive this detail?  Or do they get only the exact same data as shown on Schedule A (ie., total medical expense and the portion in excess of 7.5% of our AGI)?

Thanks for your help.
