Amounts entered are not "generated automatically." Amounts entered on your tax return are entered by the user. That is you. Either you keyed in the information yourself by hand from your 1098's, or you imported it from the mortgage lender(s). If you imported the information you have to check your entries against the hard copies of your 1098's from the lenders to make sure it is entered accurately.
