Not sure what you mean by separate. ALL of your tax return documents need to be entered on the SAME 2019 tax Form 1040. Enter a W-2 in Federal>Wages and Income
You have not said what kind of 1098 you have--is it for mortgage interest, or is it a 1098T for tuition or is it a 1098E for student loan interest--those get entered in different places.
