TT does not add Underpayment Penalties to the owed amount

TT tells me that I owe $120 Underpayment Penalties and I agree although my calculation is $124 (went through an excel 2210 form manually).

 

TT also says "The balance due on your return includes this $120 penalty"

 

Problem: That is not true. It does not include it.

 

How can I resolve this?
