1098 HELOC outstanding mortgage principal issue

I have 3 1098...1 for personal residence...1 for investment and 1 for HELOC

 

Ques 1 - I refinanced my personal residence twice in 2020 and recd. 1098 from all lenders...even though 1098 has outstanding mortgage principal, should i enter 0 or the amount from 1098 because that lender was paid off?

 

Ques 2 - Everything is fine until i enter 1098 outstanding mortgage balance Box 2 from HELOC and due to that, my return drops more than 82%. It's a small HELOC of 20k with 19k balance on investment property. Since this is a exponential drop, i wanted to check with a professional. Thanks
