I can not get form 1098 entered on my return

Look on Schedule A.

The mortgage interest goes under the INTEREST section and the real estate taxes go under the TAX section.

That would go under educational expenses in the credits/deductions section if it's a 1098T
You can also just type 1098 in the search box and it will take you to the right place (either mortgage or education section, whichever applies).

The education tuition is Form 1098-T.
