Deductions & credits

Could you clarify your last paragraph. You say "..enter the three 1098 forms on one screen" then you say "Add the interest together...". So are the 1098 forms still entered separately or just one entry? Can you clarify how the page titled "We need a bit more information to wrap up this deduction" (see uploaded screenshot) should be filled out since I have three fields for each of the three 1098 forms.
