The mortgage lender puts box 8 on the 1098 that the IRS gets a copy of. Only the dollar amounts go on a tax return that you file. The 1098 "Mortgage Interest Statement" that TurboTax produces is for your records only and is not part of the tax return that goes to the IRS so entering the box 8 information into TurboTax would serve no useful purpose so TurboTax does not ask for it.
